Get all the new features and
functionality of Mathcad 13! Building on
more than 20 years of Mathcad technology, Mathcad 13 continues
to be the standard for technical computing and engineering
calculation documentation, and provides users with unsurpassed
breadth and depth of application—enabling increased productivity
and quality. The latest release—Mathcad 13—adds to the
mathematical and ease-of-use feature set that has made Mathcad
the tool of choice for hundreds of thousands of professional
engineers and scientists. Mathcad 13 also adds expanded equation
tracing, called provenance, to Calculation Management in large
engineering organizations.
Calculation Management and Reporting
|
In
this Mathcad 13 example, a series of explicit
calculations (keywords and left-hand sides hidden) show
substituted values followed by the final numerical
result. |
NEW! Explicit Calculation
Many certification organizations require reported
calculations to show substituted values before results are
computed. Mathcad 13 introduces a new symbolic keyword,
explicit, to do these substitutions. Users can choose to
substitute some, all, or none of the defined variables in an
expression without reducing the expression numerically. Several
of these statements in subsequent calculations can show a
step-by-step trail of substitutions, followed by a final
numerical evaluation. This functionality greatly improves the
ability of a user, auditor, or organization to verify and
validate calculations.
NEW! Expanded 2D Graph trace options
A host of new line and symbol options have been added to 2D
graphs in Mathcad 13. Now users can communicate complex
technical information more clearly in visual format. One of the
most important new options is the ability to choose the plotted
symbol frequency independently from the total number of points
used to create smooth connecting lines.
The full Windows color palette, new
filled symbols, and independent control of line and symbol
weight round out the trace settings feature set. These many new
options, available through an updated, modern Windows style
settings dialog, provide precise control over graph appearance.
"The trace improvements help me automate
and streamline program development for radar systems
design, while getting to market faster in an extremely
competitive industry." -

In Mathcad 13, temperature units allow
users to express unit-checked results in common linear-transform scales.
|
NEW! Unit Functions: Temperature units,
Decibels, and Other Custom Engineering Units
In Mathcad 13, units can have a functional form. The most
important examples of this are the Fahrenheit and Celsius
temperature scales. These new units can be used to define
values, or to convert results in the unit placeholder, just like
multiplicative units. Not only can you carry and balance
functional units through calculations, you can display results
in almost any conceivable scaling to suit documentation needs.
It is possible to define your own unit functions, using them in
expressions with standard unit notation.
User-specified default units
In Mathcad 13, a whole new interface enables the viewing of
existing unit settings for base and derived units, and the
creating of a custom unit system by adding, modifying, and
deleting rules for unit simplification.
Metadata Enhancements
Mathcad 13 enhances traceability and auditability on
equations by creating annotation fields on more types of math
regions, including results and referenced files. Provenance
information is also now automatically replicated when multiple
regions are copied and pasted simultaneously.
Program Debugging and Math Functionality
Mathcad 13 introduces several important new
features for working with programs, parametric fitting, linear
algebra, and other solvers.
NEW! Program Debugging
New Mathcad functions ‘trace’ and ‘pause’ enable users to
report intermediate values in a program to a Trace Window, and optionally step or halt a program if it’s not producing the desired results. The ‘trace’ and ‘pause’ functions will output to the Trace Window when debug mode is specifically toggled on, so users can leave these functions in their programs but only use them when needed. Results from the Trace Window can be copied for reuse elsewhere.
|
The new trace function in Mathcad 13
lets users format and report intermediate program values
in debug mode. |
"The 'trace' and 'pause' statements are a
major improvement for programming. I found these very
helpful not only in debugging a program, but to check on
the program flow and partial results."

Enhanced parametric fitting
Mathcad 13 adds a number of improvements and extensions to
the genfit function. The new algorithm solves some types of
model functions faster and more accurately than the old one.
Further, the new algorithm will allow users to supply the fit
function only, without generating symbolic derivatives for each
fit parameter. This option saves time and complexity in setting
up the function, and avoids bad fits resulting from incorrect
derivatives. The function has also been extended to accept any
combination of parameter names, rather than insisting that
parameters be specified as elements of a vector. This allows
users to specify the model function using discipline-correct
notation.
Enhanced linear algebra
Mathcad 13 reduces the time required for all of the linear
algebra functions, including matrix inversion, multiplication,
linear system solution, and eigenvalue reduction.
"The linear and non-linear unit support,
temperature in particular, will be extremely useful to
our calculations where we evaluate steam and
thermodynamic process conditions."

As shown in Mathcad 13, long, complex
calculations will show the specific quantities supplied
and required in the arguments for any function call. |
Enhanced Unit Error Messages
Mathcad 13 enhances error messages for cases in which the
values supplied have the wrong units. The error messages
pinpoint the type of error and suggest the correct type of unit
so users can quickly correct their work. Unit-specific error
messages decrease debugging time, showing the quantities a
function expects for its arguments. Users can also look at
function signatures in Mathcad 13 by evaluating the function
name.
"Unit error checking is one of Mathcad's
major advantages and forces users to adopt good habits.
Improving the error checking will be a major benefit in
much of my work." - Mathcad

UI and Documentation Enhancements
NEW! Autosave
Mathcad users can now choose to Autosave their work at a
user-specified time interval, helping to manage loss of work.
NEW! Compatibility Switches
Users can set which way they would like constructs to
behave, according to version number, using the compatibility
switches. The constructs that are switchable include array
assignment of multiple variables, local assignment return value,
0/0, and the precision used for truncation functions.
New Additions to Mathcad Resources
Mathcad's online resources continue to provide hundreds of
worksheets that illustrate the depth of Mathcad's mathematical
power and the variety of applications that Mathcad supports. All
of these worksheets are live, so as you read the Tutorials or
QuickSheets you can watch Mathcad at work, change the inputs,
and see the results in the outputs as they update. The Resources
window automatically pops up the first time you start Mathcad. A
new Programming Tutorial addresses more topics in Mathcad
programming, and new QuickSheets show advanced solving methods.
NEW! Migration Guide
In addition to the traditional Help and Resources, Mathcad
13 documentation offers an important new resource for
experienced users. The Migration Guide discusses math constructs
that have been upgraded in recent versions and any
incompatibilities those may create with older versions. The
guide gives specific instructions on migrating documents
efficiently to take advantage of new functionality and remove
errors. It shows best practices to optimize documents, and
suggests methods of working with the latest Mathcad technology.
