Hello Guys ,I need a help please solve my problem.

Error while evaluating UIControl Callback. and Index exceeds the number of array elements. Index must not exceed 0.

Learn to use the debugger.

Do you want better help? Then learn to ask a question in a way that can be answered. That is, you will need to show the code that produced the error, and do so in a way that will allow someone else to test that code. Else, anyone will be forced to make wild guesses as to what you may have done wrong.

Far easier? LEARN TO USE THE DEBUGGER!

Apparently you're indexing an empty array containing 0 elements but you're asking for a value at a non-zero index. That's about as deep as we can go given the information available.

Recreation of the problem:

a = [ ];  % empty, no element
a(1)      % ask for the first element

Index exceeds the number of array elements. Index must not exceed 0.
