"WebAn m×n matrix A =[aij] is a rectangular array of numbers arranged in m rows and n columns. The entry in the ith row and jth column is written aij. More generally, such an array, whose entries are allowed to depend on an indeterminate t, is known as a matrix function. Matrix functions can be used to formulate systems of differential equations.
