view that below. If we want to use this matrix in calculations, we must be able to refer to it, so we must give it a name. To call the matrix m, we can go back to the input cell and simply insert m = in front of our matrix. Then we press Shift-Return to get the same output, except now Mathematica knows that this matrix is called m.

27.09.2015 · A matrix is an array of numbers arranged in rows and columns. In Mathematica matrices are expressed as a list of rows, each of which is a list itself. It means a matrix is a list of lists. If a matrix has n rows and m columns then we call it an n by m matrix. The value(s) in the ith row and jth column is called the i, j entry.
