As the name implies, a dot-matrix printer uses patterns of dots printed within a rectangular matrix to generate individual characters.

Matrix equivalence is an equivalence relation on the space of rectangular matrices.

On the contrary, rectangular matrices do not have the same number of rows and columns so they can never be raised to a power.

Corollary results are derived for the maximum singular values of rectangular matrices.

Two rectangular matrices that can be converted into one another allowing both elementary row and column operations are called simply equivalent.

In general, for a rectangular matrix, the rank is the number of linearly independent rows (and columns).

The pins and sockets are held in a rectangular matrix in a nylon shell.

This particular formula has the benefit that it also applicable to singular or rectangular matrices A.

It typically has 96, 384 or even 1536 sample wells arranged in a 2:3 rectangular matrix.

Above we required that A be a square matrix, but these decompositions can all be generalized to rectangular matrices as well.
