The latest version of Mathcad (13) from Mathsoft provides wider support for the company's Calculation Management Suite, which enables design teams to keep a record of their calculations and identify any possible errors made during the early stages of an engineering design project. With Mathcad 13, designers can document and capture their calculations, analyses and critical values while they create them, providing a repository of data for audit purposes, which can also be reused in other design projects to enhance productivity.Among its many new features, Mathcad 13 has powerful new program debugging capabilities, including an ability to insert traces and step through program loops for audit and verification purposes. It includes improved 2D plot graphics with an easy-to-use customisation menu for special line types, symbol markers and colours. The software supports non-linear units such as Fahrenheit, Celsius and Decibels for the first time, and allows users to create custom units via an easy-to-use menu.Brian Patterson, an electrical engineer with Panasonic Plasma Display Laboratories in the USA, says the new graphing enhancements in Mathcad 13 have enabled him to make much cleaner presentations. The new dual Y-axis capability has also allowed him to plot feedback gains and phase lines for display in a single graph. The performance gains enable us to perform iterative calculations on our magnetic component designs even faster. And as always, we're relying heavily on Mathcad's ability to display mathematical expressions in their natural form, with informative annotations to assist reuse and collaboration. All UK academic users and single-user licence customers for Mathcad 13 are supplied and supported by Adept Scientific.
