dimension mismatch error in for loop

Following is the overview of my problem

for i=1:iterations
  compute XYZ
end

Each computation of XYZ is independent and has nothing to do with number of iterations. To be precise I am computing some error per iteration. The problem is that when I change the number of iterations, I get a dimension mismatch error at some random value of i. I dont understand what is wrong here because the loop is doing the same stuff for iterations = [10 100 1000] so if it can work for 100 iterations then why not for 1000 or more. My code has a lot of nested loops and I was wondering if variables get messed up . In that case should I clear them at the end of each function.

Without seeing the failing code, it is impossible to guess, what's going wrong.

hi xplore29

maybe you are using a complex number "i" during the XYZ compuatation, if so, change it to "j" or sqrt(-1) and try again .

I am using an exp(.) in my computations. No complex number is involved.
