WebThe second type of mathematical operator we will study is the operation assignment variant. This is similar to the binary operator but will assign the result of the operation to the object calling it. Hence instead of creating a separate matrix C in the equation C = A + B, we will assign the result of A + B into A. WebDec 21, 2024 · A matrix is a two-dimensional data object made of m rows and n columns, therefore having total m x n values.
