The I/O functionality of C is fairly low-level by modern standards; C abstracts all file operations into operations on streams of bytes, which may be "input streams" or "output streams". Unlike some earlier programming languages, C has no direct support for random-access data files; to read from a record in the middle of a file, the programmer must create a stream, seek to the middle of the file, and then read bytes in sequence from the stream.In case of matrix.h, Dynamic Memory Allocation used to allocate memory space for storing matrix elements. User defined datatype intmatrix and doublematrix are introduced here for purpose of matrix operations easily.

User defined datatype intmatrix and doublematrix are introduced here for purpose of matrix operations easily. Before matrix.h, there was no such ANSI accepted header file for matrix operations in C.In case of MATLAB, Python or some other languages, there are some library functions, namespace or packages are available.
