This array stores the dimensions of the input.
input_dimensions[0] would store the batch size
input_dimensions[1] would store m
input_dimensions[2] would store n
input_num_of_dimensions is how many dimensions there are, which read_dims() returns at position [0].
In the case for the input matrix, it has 3 dimensions. So memory is allocated for 3 integers(an array of 3 elements)
When allocating memory, it must be freed at the end of the program. e.g. free(input_dimensions);
/*Code for reading and writing to the files*/
/*Gets the dimensions of the matrices. This will return a 1d array of 4 elements [0] = number of dimensions [1] = batch [2] = m [3] = n*/
