What happens when you multiply identity matrices with different dimensions?

As a result of the first two rules, If an identity matrix is multiplying a square matrix of the same dimensions, the result will also be a square matrix which will be the same as the non-unit matrix of the multiplication, no matter the order in which the matrices are being multiplied with one another.

How to multiply a 1×1 matrix?

By this logic, we should only be allowed to multiply a 1 × 1 matrix by either a 1 × n matrix on the right or a n × 1 matrix on the left. However, if C is a 1 × 1 matrix and D is a m × n matrix, where neither m nor n = 1, we’re allowed to multiply the 2 matrices simply by multiplying each entry in D by the entry in C.

How do you multiply 2×3 matrix times 3×1 matrix?

You can multiply a 2x 3 matrix times a 3 x1 matrix but you can not multiply a 3x 1 matrix times a 2 x3 matrix. The dimension of the matrix resulting from a matrix multiplication is the first dimension of the first matrix by the last dimenson of the second matrix. Multiplying a 2 x3 matrix times a 3x 1 matrix yields a 2 x 1 matrix.

How do you find the product of two 3×4 matrices?

Multiplying a 3 x4 matrix times a 4x 2 matrix yields a 3 x 2 matrix. The product of two matrices is found by adding the row elements multiplied times the column elements. Example 1: Note: (1×2)• (2×1) → (1×1) matrix.
