I need to make a matrix[i][j] in C which will read from a file with the format bellow:
1,3.567,4.893,1.756
2,7.875,8.872,4.438
3,8.234,9.987,3.908
.
.
.
so as the matrix[0][0]=1, matrix[0][2]=4.893, matrix[2][1]=8.234 and so on ...
can anyone help me in how to allocate memory and read the file
Thanks
Do you KNOW that you always have three columns?
If so, you could use realloc on a float/double [3] array.

Compilers can produce warnings - make the compiler programmers happy: Use them!

The num of rows and columns will be different
Then you need some way of determining how many columns there are, and use a 2D dynamic array - common question here, so search the forum for an answer. It's certainly a lot easier to solve this sort of problem if you know a max size that it may be, but I also understand that this is not always feasible.
