Mastering Mathcad: Matrix Operations Made Easy | Step-by-Step Guide

[Antwan718]

Hello I am trying to teach myself how to use mathcad and am having some issues.

I am trying to sum the rows and cols of a matrix respectively.

using i for the row index and j for the col index.

I have as of now defined a variable sum eiether row or colum and am using a summation of k=0 to n-1 rows for each matrix. I see that what I am intending on doing is being preformed but only on the last row and col of an n-by-m matrix.

Any help would be appreciated.

You can use the summation command.

In Mathcad 2000 at least, arrays start at 0 by default, not 1.

Well out of date, but resurrecting old threads is sometimes fun!
