how to create new matrice step by step

[joefx23]

hi
sorry my english is not so good.

i have the following problem

for ind=1:1:length(Phiw)
if Phiw(ind) > 0
[Phiw2(ind) := Phiw(ind)-180]
else
[Phiw2(ind) := Phiw(ind)]
end
end

i want to check whether phiw is positive and substract 180 if it is

but matlab doesnt like the 'Phiw2(ind) = ' statement..

i hope you understand what i want to do.
what can i change that it works? or is there an easier way?

btw: Phiw is createt by a negative arctan...

thanks joe

Phiw2 = Phiw2 - 180.*(Phiw2>0)
