use rand in editor

I was given a script to edit with the function "randi" in it, i have a older version of matlab R14. It worked on the latest version, curious if there is n easy conversion to fix this issue.

Are you saying that you got a script with randi() in it from someone who uses R2012a, but you don't have randi() in your older version of MATLAB and so you want some code that does essentially the same thing?

yea that is right

if i change the randi() to rand() which my version can handle it errors with matrix not being the same and rendering mesh

You can define your own randi like this:

function out = randi(iMax, rows, columns)
  out = int32(floor(iMax*rand(rows, columns) + 1));

Of course that is not as flexible in the types of input arguments that the real randi() accepts, but you can work on that if you want.
