Entermatrix

Function: entermatrix (<m>, <n>) Returns an <m> by <n> matrix, reading the elements interactively.

entermatrix;

If <n> is equal to <m>, Maxima prompts for the type of the matrix (diagonal, symmetric, antisymmetric, or general) and for each element. Each response is terminated by a semicolon ; or dollar sign $.

If <n> is not equal to <m>, Maxima prompts for each element.

The elements may be any expressions, which are evaluated. entermatrix evaluates its arguments.

          (%i1) n: 3$
          (%i2) m: entermatrix (n, n)$

Is the matrix 1. Diagonal 2. Symmetric 3. Antisymmetric 4. General Answer 1, 2, 3 or 4 : 1$ Row 1 Column 1: (a+b)^n$ Row 2 Column 2: (a+b)^(n+1)$ Row 3 Column 3: (a+b)^(n+2)$
