mathsisfun.comYours, Rod PierceOr try (just a guess) in Octave:Try the Matrix Calculator: http://www.mathsisfun.com/algebra/matrix-calculator.htmlHi,Don't know Octave, but to multiply you need to match internal col to row such as [3x2] by [2x3]
A = [1,2,3; 4,5,6];
B = [7,8; 9,10; 11,12];On 25 October 2015 at 16:50, <address@hidden> wrote:Sender: Jonathan Camilleri

I am reading your tutorial on matrix multiplication, as a teacher, and, I am trying the following using Octave however Octave is reading that the matrices are incompatible.
>> A = [1,2,3; 4,5,6];
>> B = [7,9,11;8,10,12];
>> C = A*B;
error: operator *: nonconformant arguments (op1 is 2x3, op2 is 2x3)
Having asked the Octave forums they seem not to have seen any mathematical error from their part, would you kindly elaborate with mathematical theory and proof please?
Octave is available by searching online and so are tutorials.
I shall await your reply as I want to confirm whether there is a bug or a mathematical inaccuracy.
