Hello everyone,

I am new in the world of Cplex and Matlab and I apologize for every easy question I ask or for every mistake I do.
I have a quadratic program with linear constraints.

[x,fval] = cplexmiqp(H, f, A, b', Aeq, beq', [], [], [], lb, ub, 'B' ,[],options)

my matrix H is actually not symmetric but I fixed this with setting H = H+H'.
Now I would like to say Cplex/matlab that every of my variables x should be binary but I dont know how.
Actually I dont even need my function f but when I write [] instead of f it always says:

Error using cplexmiqp
CPLEX encountered arrays with inconsistent lengths.

Can please anybody help me ?
I am thankful for every advice.

Best regards !
 

Did you take a look at the reference documentation of the function here?

Or at the many example that ship with CPLEX? The example in cplex/examples/src/matlab/cplexmiqpex.m should tell you exactly what to do.

Thank you very much for your quick answer. I am sorry that I did not find any examples before but now I fixed it and everything is working with this issue.
But maybe you can help me with my other problems. I can not fix this so far and I hope that my questions there are not so obvious.

I hope you can help me with my problem where I receive the error that this is not convex. I have no other idea there.
