I'd suggest you write a small C app, or script (AWK, Pearl, etc), and process that table into a ''C'' format that you can #include into your compilation.

int MyTable[10][10] = { { 1, 2, 3, .. }, .. , { .. } }; Alternatively if you have some file storage (SD Card, FatFs, NAND), you could store the text output from MatLab as a file, and simply parse that data into a structure/table at run time.

My table have a big size, i can't write it manually, i found a function called fopen but i didn't  know how to use it

some components of table are: 523 528 536 496 452 439 433 439  ............................. 200 column 250 658 025 ............................................ .................................. 140 Row Thanks

Yeah, I'd class the app/script method as ''mechanical''. The STDIO and fopen/fread/fclose, and file handling concepts are pretty fundamental CS stuff.  Try this, or Google for some others.
