Hello!
I have the following set of linear equations:
2x - y + 3z = 6
-4x + 2y -z = -7
2x + y + 5z = 6
I made the matrixes:
A = [2, -1, 3; -4, 2, -1; 2, 1, 5]
B = [6,-7,6]
and then, to solve the set of linear equations, do:
A \ B
but get the error:
error: operator \: nonconformant arguments (op1 is 3x3, op2 is 1x3)
error: evaluating binary operator `\' near line 16, column 3
or
inv (A) * B
and get the error:
error: operator *: nonconformant arguments (op1 is 3x3, op2 is 1x3)
error: evaluating binary operator `*' near line 16, column 9
So what's wrong? Thanks!
