What is wrong with the code ?

1 view (last 30 days)
i've got the base equations on the first 3 rows and the gauss-seidel on the last 3 rows , i tried writing a code that's like this ... and i get an error message
x1 + 5x2 - 6x3 = 5
3x1 + x2 + 5x3 = 23
x1 + 4x2 + x3 = 7
x1=(23-x2-5*x3)/3
x2=(7-x1-x3)/4
x3=(x1+5*x2-5)/6

Remove the
i = i+1;
that immediately follows the while ,,, instruction.
otherwise, first time in to the loop you are trying to set x1(3) = (23 - x2(2) - 5*x3(2))/3, but you have yet to specify x2(2) and x3(2).
