I already specified that we use information found online. I referred to the
Octave documentation.
Here it's my work script:
global w5 = 5.83*72; h5 = 8.27*72; lm = 0.78; rm = 0.3;
global wb = 504; hb = 662; lb = 71; tb = 43; rb = 433; bb = 604;
rb = wb-rb;
bb = hb-bb;
function y = f(x)
y = zeros(3,1);
global w5;
global wb;
global lb;
global rb;
global lm;
global rm;
y(1) = w5 - x(1)*(wb+x(2)+x(3));
y(2) = x(1)*(x(2)+lb) - 72*lm;
y(3) = x(1)*(x(3)+rb) - 72*rm;
endfunction
[x, info] = fsolve (@f, [1; 3]);
When i run this script i got this error:
error: A(I): Index exceeds matrix dimension.
error: called from:
error: f at line 33, column 7
