where n m p denotes the dimensions n m and m p k1 and k2 denotes the number of non zero elements in matrix a and b
##Generating Random input
If you want to create two random sparse matrices of dimensions n,m and m,p follow these steps.
$ git clone https://github.com/hackerkid/parallel-matrix-multiplication
$ cd parallel-matrix-multiplication
$ g++ create_matrix_mul_input.cpp
$ ./a.out
n
m
p
where n, m, p are the dimensions of the matrices. The program creates an input file called input.in of the for
