You're saving the entire workspace. Why don't you pass in some variable names (in single quotes) to save only what you really really need. How large are these variables? Hundreds of millions of bytes? Also, you forgot to tell us the exact error message or exact code, so I'm going to refer you to this: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer

i repeated the operation with passing the variables needed in order to reduce the volume the variable's size is 92.4 Mo (98 877 786 octets) and everything is Ok :), but i still have a question why it doesn t work manually ?
