How to find square root of a matrix

How do you find the square of an each individual element of a matrix.

Based on the title of the post, I assume you mean the square root of each individual element of a matrix.

thank you btw this only works for square matrixes.

mine isn't square.

I didn't bother trying that, because I assumed it would not work. I'm a little surprised it does!

Not even sure why I tried it!

Ziyad,

Just a comment, in your prior posts I think you commend on the speed of the calculaitions.

In the Help, something like "features in depth", they talk about using the vectorize operation and it being slow, so if you are dealing with large matrices the program that Richard provided is recommended. In your prior posts the vectoirze operator is used a lot, it looks nice, but maybe to speed up you might want to replace some of the operations with a program.

Are you sure? Vectorising is generally faster than an explicit loop. For this example, that is certainly the case.

Richard,

I havn't tested it, but please look at Quicksheets>Mathcad Techniques>Improving Calculation Speed.

If it is a natrual vectorization that is prgramed by Mathcad, it is fast, but using the vectorization operator, it is suppose to be slower.

Please let me know what you think.
