Is this the same question or a different question than http://www.mathworks.com/matlabcentral/answers/28624-error-using-256x256matrix
Neither of the questions has enough information about what has to be done for there to be a meaningful response.
This is for PSO, right?

Need to be more specific, like do you have special requirements for the entries that you want it to be 0's?
Simply put, a(i,j)==0 makes entry (i,j) in matrix a 0.
