I have mathcad 2000. The resource center provides three programs that perform the three elementary row operations on a matrice. So its not to hard to do the algebra performing the elementary row opwerations (one at a time) on a matrix to reduce it to row echelon form. Of course none of that is necessary since all you need to do is type rref[M] = (where M is the name of the matrice) and mathcad will automaticaly solve the system. But as a challenge I would like to be able to use those three row operation programs to perform several operations at once. For example suppose I want to multiply a row by a scalar,interchange two rows, and add the scalar multiple of one row to another, all at the same time. You can do this on a TI 89 calculator and it is so simple. Any suggestions?

You're about 12 years behind the times!

What are your row programs? Post a sheet showing each one. (In general, you can nest one function inside another; the inner one will execute first, the outer one will operate on that result.

You can also get a free 30 trial of the latest versions!

Wasnt expecting an answer so quickly, thankyou. I think I found a good discussion site. the programs I have are taken directly from the "rescourse center". Even to do a simple operation like multiply a row time a scalar, you have to use one of the three programs. I can barely read the program and understand what it is doing. I also cant show them here because I only have access to the internet at the library computers. But I will get back with you on this and will find a way to execute several row operations at the same time by consolidating (nesting I guess they call it) the three little programs that I have. And when I do that (even though the software I have is 12 years old) it will be university level mathematics combined with a commanding knowledge of computers and machine language. Something that fewer than five percent of computer users in the world today can say.
