error using reshape , number of elements must not change

i have this problem ! can some one help me plz ....

Set an error breakpoint and run your code. When MATLAB stops on line 36 of your xOCDMModem_TX.m file, show us the following information:

• The size and class of the t_ModemSymbol variable
• The values of the num_Symbol and num_Block variables

I'm guessing that t_ModemSymbol is the same size and class as the t_ModSymbol variable, namely a 163840-by-1 complex double array. If it is, then num_Symbol times num_Block must be exactly 163840 for that reshape command to succeed. If num_Symbol is 2^6 (a guess based on how t_ModSymbol is defined on line 162 of your main_amani.m file) numBlock should be 5*2^9 or 2560.

An alternative could be to use the buffer function.

For example —

t_OCDMSymbol = buffer(t_ModemSymbol, num_Symbol);

It will fill the unused element positions with zeros.
