generating random elements

Hello All,

Could anybody help me with this question please?

I have a matrix "M" with five elements. I want to generate 10 (for example) matrices such that each element is randomly within +/- %5 of the corresponding element of the matrix "M".

Thank you in advance

You may use something like this for a single value or matrix

You may also turn this procedure in a function

and use this function to create ten sets using a range variable

        Nice and Simple, Werner! The hallmark of a Good Worksheet 🙂

        I'm too lazy to type out the range variable, though ...
