My MATLAB when start my run said this one:
??? Warning: Struct field assignment overwrites a value with class "double".
See MATLAB 7.0.4 Release Notes, Assigning Nonstructure Variables As Structures Displays Warning for details.
Do you Know what's the problem? The version of MATLAB

Use
>>dbstop if warning
and re-run the code to find the command that is causing it.

My guess is you're reusing a variable name, for example
a = 1;
a.b = 2;
The warning is letting you know that by assigning a field b to the variable a, you are overwriting the double array a with a structure array named a. If you do initialize the structure first, it will avoid the error.
a = 1;
a = struct;
a.b = 2;
