Hello, I'm getting the error 'Subscripted assignment dimension mismatch.' for this piece of code:
a = -3;
b = 3;
M = 10^(5);
nrs = a + (b-a)*rand(2*M,1);
rng(:,1) = (nrs(1:length(nrs)/2));
rng(:,2) = (nrs(length(nrs)/2:end-1));
Could anyone help me to figure out what is wrong and how to fix it? Thank you very much.

Your code as you posted it runs for me without error. Check to be sure you haven’t defined ‘rng’ earlier in your code.
Also, rng is a built-in MATLAB function, and you are ‘overshadowing’ it by naming your variable the same. Rename your variable something else, like ‘nrs_rng’.
