Hướng dẫn php multiply two variables - php nhân hai biến

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.

Độ phức tạp về thời gian: O (N3). Nó có thể được tối ưu hóa bằng cách nhân ma trận Strassen O(n3). It can be optimized using Strassen’s Matrix Multiplication O(n3). It can be optimized using Strassen’s Matrix Multiplication

Không gian phụ trợ: O (N2) O(n2)O(m1 * n2)

Sự nhân của ma trận hình chữ nhật: & nbsp; chúng tôi sử dụng con trỏ trong C để nhân với ma trận. Vui lòng tham khảo bài đăng sau dưới dạng điều kiện tiên quyết của mã. Làm thế nào để chuyển một mảng 2D dưới dạng tham số trong C? & NBSP;We use pointers in C to multiply to matrices. Please refer to the following post as a prerequisite of the code.How to pass a 2D array as a parameter in C?
