Matrices c and d shown below are equal
WebMatrix E is 1 by 2, one row times two columns. Matrix A is a 2 by 2, two rows and two columns, and so this would have been defined. Matrix E has two columns, which is exactly the same number of rows that matrix A has. And this really hits the point home that the order matters when you multiply matrices. http://algebra.nipissingu.ca/tutorials/matrices.html

WebRow Echelon Form. A matrix is in row echelon form (ref) when it satisfies the following conditions. The first non-zero element in each row, called the leading entry, is 1. Each leading entry is in a column to the right of the leading entry in the previous row. Rows with all zero elements, if any, are below rows having a non-zero element. http://scipp.ucsc.edu/~haber/ph216/rotation_12.pdf
