On the theme of "If you liked that, you'll like this", here's a (somewhat messy) worksheet that introduces functions to replace or augment Mathcad's built-in matrix, CreateSpace and CreateMesh functions. They make it easier (for me, at least) to evaluate functions, and plot functions in 3D, and get the correct x and y axis values.
Expand the Utilities Area to see their definitions - it's not neat because it's a development (ie, "making stuff up as I go along") worksheet.
