WebOct 6, 2024 · Recall that a matrix is a rectangular array of numbers consisting of rows and columns. We classify matrices by the number of rows \(n\) and the number of columns \(m\). For example, a \(3\times 4\) matrix, read “3 by 4 matrix,” is one that consists of \(3\) rows and \(4\) columns. ... The determinant of a matrix is a real number. The ... WebIf we know that row operations don't change the determinant and that the rref of an invertible matrix (which is a triangular matrix) is the identity matrix, wouldn't that mean that all invertible matrices have a …
