Cho hai ma trận, nhiệm vụ để nhân chúng. Ma trận có thể là hình vuông hoặc hình chữ nhật.
Examples:
Input : mat1[][] = {{1, 2}, {3, 4}} mat2[][] = {{1, 1}, {1, 1}} Output : {{3, 3}, {7, 7}} Input : mat1[][] = {{2, 4}, {3, 4}} mat2[][] = {{1, 2}, {1, 3}} Output : {{6, 16}, {7, 18}}
Phép nhân của ma trận vuông: & nbsp; chương trình bên dưới nhân hai ma trận vuông có kích thước 4*4, chúng ta có thể thay đổi n cho các kích thước khác nhau. & Nbsp;The below program multiplies two square matrices of size 4*4, we can change N for different dimensions.
