Even though two-dimensional arrays are similar to matrices from linear algebra, operations (such as multiply) have nothing to do with the operations in linear algebra (such as matrix multiplication).
虽然二维数组与线性代数中的矩阵类似,但是对它们的操作(比如乘)与线性代数中的操作(比如矩阵乘)是完全不同的。
OK, so we've seen how to multiply matrices, and how to write linear systems in matrix form.
我们学过矩阵乘法的,以及用矩阵表示线性方程。
