Error in my Image COMPRESSION code USING DCT2D in matlab

I'm trying to fix a program already exists, but there is always this error

"***Error in ==> DCT1 at 254 decm_eq BIN2DEC = ([I_runcode (a, b) code (1 + m * (c_indx-1). M * c_indx) DEC2BIN (0 bpp_diff)]).***

I do not know what to do.

My source code is here: http://stackoverflow.com/questions/18299035/error-in-my-image-compression-code-using-dct2d-in-matlab

Please help me

The line you indicate in the error message does not exist in the source code you posted. The closest there is to it in your source is

decm_eq=bin2dec([I_runcode(a,b).code(1+m*(c_indx-1):m*c_indx),dec2bin(0,bpp_diff)]);

In order to have a realistic chance of figuring out what the error is, you need to post the actual error message, which might (for example) look like

Attempt to access structure field of non-structure element

or perhaps

index out of range

or perhaps

undefined function or variable dec2bin

I just send you by mail the entire file. Thank you for your reply.
