Which library in C provides functions for mathematical operations on matrices?<string.h><stdlib.h><math.h><matrix.h>

The library in C that provides functions for mathematical operations on matrices is typically <matrix.h>. However, it is important to note that this library is not part of the standard C library and may not be available in all environments. Standard C does not include a built-in matrix library, so many developers create their own implementations or use third-party libraries, such as LAPACK, Eigen, or others, for handling matrix operations. The libraries you mentioned, such as <string.h>, <stdlib.h>, and <math.h>, serve other purposes: string handling, memory allocation, and basic mathematical operations, respectively.

In summary, for matrix operations specifically, look for a library that directly supports matrices, commonly referred to as <matrix.h>, or consider using a numerical computing library tailored for these tasks.
