Matrix Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans
What Is a Matrix Calculator?
A Matrix Calculator is a tool that allows users to perform various operations on matrices such as addition, subtraction, multiplication, inversion, and more. In South Africa, this calculator is invaluable for students studying mathematics, engineers, economists, and anyone working in data analysis or computer graphics. Everyday examples include calculating the total sales for different products over a month, optimizing resource allocation in a project, or simulating population growth.
How to Calculate Matrix Manually
The formula to calculate the product of two matrices involves multiplying corresponding elements in rows and columns to obtain the resulting matrix. For example, to multiply a 2×2 matrix by another 2×2 matrix, you would multiply the first row by the first column, and the first row by the second column, and so on.
For South African values, let’s consider the following matrices:
Matrix A = [[2, 3], [4, 5]]
Matrix B = [[1, 0], [0, 1]]
The product of A and B would result in a new 2×2 matrix as follows:
Matrix C = [[2*1 + 3*0, 2*0 + 3*1], [4*1 + 5*0, 4*0 + 5*1]]
Matrix C = [[2, 3], [4, 5]]
