creating a Function for an optimizing algorthim

Hello,

Is this function correct?...i.e when it is called will it employ the given values of a,b,c in the stated expression

function y=Roughness(a,b,c)

    y=2.29587 -  0.016361 * a + 5.94470 * b - 1.75990 * c -0.034286 * a * b + (4.76190*10.^-004)*a*c +1.66667*b*c + (5.75411*10.^-005)*a.^2 - 1.61095*b^2 + 2.80631*c^2;

for a = '[56; 80; 115; 115; 174; 115; 80; 115; 80; 150; 150; 80; 115; 115; 115; 115; 115; 150; 115; 150]'; end for b = '[0.16; 0.08; 0.03; 0.16; 0.16; 0.16; 0.23; 0.16; 0.23; 0.23; 0.23; 0.08; 0.16; 0.16; 0.28; 0.16; 0.16; 0.08; 0.16; 0.08]'; end for c = '[0.60; 0.90; 0.60; 0.60; 0.60; 1.10; 0.30; 0.10; 0.90; 0.30; 0.90; 0.30; 0.60; 0.60; 0.60; 0.60; 0.60; 0.90; 0.60; 0.30]'; end end
