A different m x n matrix as output. (In other words, each elementary row operation is a map from Mmxn(R) to Mmxn(R). There are three types of elementary row. Elementary Operations. There are three kinds of elementary matrix operations. Interchange two rows (or columns). Multiply each element in a row (or column) by a non-zero number. Multiply a row (or column) by a non-zero number and add the result to another row (or column).
