Hi,

I have 100 iterations, 50~100 variables. I want to flush out all variables before each iteration. I am doing now like variable1=[];variable2=[] ---variable100=[];. But I want to know is there any command which can do this in a single command.

many thanks in advance,

100 variables! That is a poor way to write code. You should put all of your variables in a structure: this would be easier to manage, and makes tasks like this trivial.

Mekala - why do you have one hundred variables? Can't you use an array or matrix to store all of this data in one convenient variable? For example, if each variable is of the same dimension, say mxn, then you could create an mxnx100 array as

variableData = zeros(m,n,100);

Else, if each variable is of a different dimension, then just use a cell array to store all of this data as

variableData = cell(100,1);
