How to generate non repeating random numbers

Hi, I have a matrix of size 270x360 ,what i need to do is generate any random location in that matrix such that all the locations of that matrix are generated at least for once.Is that possible.If so can anybody please help me with it? Thank you, Deepa

A=zeros(270,360)

The locations of the matrix A are 1:270*360 (using linear indexing)

n=270*360
random_location=randperm(n)

If you want subscript indices ii and jj use ind2sub function

[ii,jj]=ind2sub(size(A),random_location)

Thank you for your response sir, but how do we get the index values?
