/***** The prompt i have is : use a class with 3 member functions named InputMatrix, Calculate, and OutMatrix. The program will prompt the user to (e)enter the matrix data, (c) to calculate the matrix multiplication, (d) to display the input and output matrices, and (q) to quit. no exit() …
hi Am trying to write a C-code that multiply two matrices but i want the elemnets of every matrix is random number using time function main() { srand ( time(NULL) ); int m1[10][10]; m1[10][10] = rand() % 10; scanf("%d%d",&r1,&c1); scanf("%d%d",&r2,&c2); if(r2==c1) { . . . . } this is the …
Hello, I have a 512x512 matrix and I need to split it int 16x16 blocks.. How many blocks will I therefore produce? I've tried 8 blocks of 16x16 but this does not look right when outputting the complete matrix.. Any ideas? Thanks :)
