I am asking this question because I failed to solve it myself and hope someone can give me any suggestion.

My problem is:

my program includes 3 parts:

part-1: video encoder,
part-2: channel coding - also call to a mex-files: complie from C-function "encodeBits.c" to Matlab-mexfile "encodeBits.mexw32",
part-3: video decoder.
I also perform 4 checks:

check 1: part-1 + part-2 as a whole. it means without channel coding, program works well.

check 2: pseudo an input to part-2, it means part-2 stays alone. part-2 works well.

part-2 still works well even under this condition:
possible array: **632** MB (6.623e+08 bytes) *
Memory available for all arrays: **1054** MB (1.105e+09 bytes) **
Memory used by MATLAB: 653 MB (6.842e+08 bytes)
Physical Memory (RAM): 2795 MB (2.930e+09 bytes)
check 3: part-1 + part-2 + part-3 as a whole.

memory before part 1 runs:
Maximum possible array: 877 MB (9.199e+08 bytes) *
Memory available for all arrays: 1265 MB (1.326e+09 bytes) **
Memory used by MATLAB: 441 MB (4.628e+08 bytes)
Physical Memory (RAM): 2795 MB (2.930e+09 bytes)
memory before part-2 runs, means after part-1 finished:
Maximum possible array: **869** MB (9.107e+08 bytes) *
Memory available for all arrays: **1270** MB (1.332e+09 bytes) **
Memory used by MATLAB: 430 MB (4.511e+08 bytes)
Physical Memory (RAM): 2795 MB (2.930e+09 bytes)
and it results error right after part-2 starting with error
Error using encodeBits
Out of memory. Type HELP MEMORY for your options.
check 4: tried part-2 alone again after clear all variable from check 3 it still results error

Error using encodeBits
Out of memory. Type HELP MEMORY for your options.
check 5: close Matlab window, open Matlab window and run part-2 alone it works well.

So, I cannot understand why it happens, I tried to search hard but I still cannot solve it. On the other hand, I dont understand, why part-2 can work perfectly under low resource as check 2, but part-2 doesn't work under higher resource as check 3. Thank you.
