need to be maintained. When dealing with a matrix, rules allow you to: Switch the rows of a matrix. Multiply a row by a nonzero number. Multiply a row by a nonzero number and add it to another row. For example, in the matrices listed below, the original matrix becomes the transformed matrix using the row operation 3 · row 1 + row 2.

Jan 20, 2009 · We have defined operations for adding, subtracting and multiplying matrices. Matrix inversion is the matrix analog of division. For a square matrix, A, we define a matrix inverse, A-1, by the following equation. [48] If we have a matrix equation, Ax = b, we can, in principle, solve this equation by premultiplying both sides of the equation by A-1.
