MATLAB: How to add zero infront of number

MATLAB

Hi,

I have to add 0 before a number let say num = 2. I want to show as num=02

I don't think you can pad zero for a numeric number but you can do it when printing. For example

fprintf('num = %02d\n',2)

Is this what you want? HTH

A = [0 1 0 1 0];
A = [A, zeros(1, 23-length(A))];

Just get the edit box contents and set the 0's to nulls:

editBoxContents = handles.edit1.String;
editBoxContents(editBoxContents == '0') == []

If you want the number, just add

theNumber = str2double(editBoxContents);
