Given square matrix, and solution vector, find the values of the variables
xyz = [1 -1 2; 0 2 5; 4 0 -3]; //x-y+2z; 2y+5x; 4x-3z
abc = [21; 21; 21]
y_correct = [ 9 -2 5 ];
Test suite needs to be fixed.
yeah, you're right. I'll edit later after office, thanks
only wrong solutions accepted by testsuite (on the other hand, +1 if this was in fact the intention, that was original!)
Create a square matrix of multiples
Make a random, non-repeating vector.
