MatAlloc, MatAllocBlock
MATRIX MatAlloc(int cM, int cN);
MATRIX MatAllocBlock(size_t cR, size_t cC);
cM, cN in: required matrix dimensions
Return value
Returns a pointer to the newly allocated cM × cN matrix, or NULL if the allocation
failed, or if cM was 0. Use MatFree to free the matrix.
Description
MatAlloc(a,b) is the macro version which maps to MatAllocBlock(a,b).
