function [ h ] = LinConOp( x )
x0 = [-1,1];
lb = swtMinWt1;
ub = swtMaxWt1;
Aeq = swt_Aeq;
beq = swt_beq;
A = swt_A;
b = swt_b;
[x,fval] = fmincon('objfun',x0,A,b,Aeq,beq,lb,ub);
end
it shows errors for the x's and the fval. what am i doing wrong here?

You’re passing x as an argument to LinConOp and aren’t assigning h so your function isn’t returning anything.
I suspect the fval error results from fmincon not knowing what objfun is. It’s not in the LinConOp function workspace.

I do not understand why you have all these calls in a function (LinConOp). The function does not see the parameters that are (presumably) in your MATLAB workspace.
Can you try to just run your commands at the MATLAB command line, not inside a function?
