Write a program that implements matrix multiplication in a multi-threaded environment. You may use the following definitions and function prototypes:

//N threads pthread_t threads[N]; //A, B, C matrices double **matrixA, **matrixB, **matrixC; //function prototypes int main(int argc,char *argv[]) //read N, M, and L as command-line arguments void initializeMatrix(int r,int c, double **matrix); //initialize matrix with random values void printMatrix(int r,int c, double **matrix); //print matrix void *multiplyRow(void* arg) //thread multiply function //creating N threads, each multiplying ith row of matrixA by each column of matrixB to produce the row of matrixC for(i=0;i
