WebThe area of the little box starts as 1 1. If a matrix stretches things out, then its determinant is greater than 1 1. If a matrix doesn't stretch things out or squeeze them in, then its determinant is exactly 1 1. An example of this is a rotation. If a matrix squeezes things … WebThe determinant can be viewed as a function whose input is a square matrix and whose output is a number. If n is the number of rows and columns in the matrix (remember, we are dealing with square matrices), we can call our matrix an n × n matrix. The simplest square matrix is a 1 × 1 matrix, which isn't very interesting since it contains just ...
