Write the API function TMatrix readMatrix ( char filename); that takes as input a filename, and read a matrix from the file. The dimensions of the matrix and data are in the file. See the source code of the program that generates the matrix file for details. Failure of file operatoins or memory allocations is a fatal error. The function returns a matrix.

The program mf-generate is provided to generate matrices-it helps you understand the format of the matrix data file. (provided below)

#define TElement int typedef struct Matrix { unsigned int nrow; unsigned int ncol; TElement **data; TMatrix; where nrow and ncol are numerical attributes representing the numbers of rows and columns of the matrix and data is a pointer to an array of row pointers. Each row pointer points to an array of elements of TElement type. TElement is defined as int
