Multiplying matrices.

This property states that if a matrix is multiplied by two scalars, you can multiply the scalars together first, and then multiply by the matrix.

Returns a matrix from an array-like object, or from a string of data. A matrix is a specialized 2-D array that retains its 2-D nature through operations.When multiplying two matrices, the number of rows in the left matrix must equal the number of columns in the right. For an \(r\times k\) matrix \(M\) and an \(s\times l\) matrix \(N\), then we must have \(k=s\). This is not a problem for square matrices of the same size, though. Two \(n\times n\) matrices can be multiplied in either order.
