calling function output variable names from a defined vector

i am defining very simple constraints function as below:

function[c_1 c_2 c_3] = nlcon(m)

c_1 = -0.875 + m(1) - m(2) + 1.75

c_2 = -1.75 - m(1) + 2*m(2) - m(3)

c_3 = -0.875 - m(2) + m(3) + 1.75

end

but instead of inserting the output variables manually (c1, c_2, c_3), i would like to define a set containing a variable number of constraints and i want to call the output variables from this sit. for example :

function [c] = const(m);

for i=1:3;

if i ==1;

c(i) = -0.875 + m(i) - m(i+1) + 1.75;

elseif i == 3;

c(i) = -0.875 - m(i-1) + m(i) + 1.75;

else

c(i) = -1.75 - m(i-1) + 2*m(i) - m(i+1);

end

end

but i get a wrong definition, any help?

then i tried to include that in the out

Make sure you are saving the function as a code file (hit new function and enter and save the function there...not the command line)

yeah i did but the problem is that i cant call the output functions from a set of names
