My function is not giving any output

count=0
for i9=1:length(v9);
    [MTotal9] = MTotalSolver(Tp9(i9),Hs9(i9));
count=count+1
end

the above lines are not giving me any output and getting and index error dimension

How are v9, Tp9, Hs9 and MTotalSolver defined ?

(the brackets around MTotal9 seem to be useless)

@Casper Stroem: what function?
