Failed to eliminate a call to the MATLAB function 'quadprog'.

Hi,

I'm using the Matlab 2011b, and I want to generate the function 'quadprog' provided by "Optimization Toolbox"into C code. Part of my script(.m) is as follows：

    coder.extrinsic('quadprog'); 
    x = zeros(3,1);
    x=quadprog(H1,C1,A1,B1,[],[],LB1,UB1);

But, I got the error like that:

Failed to eliminate a call to the MATLAB function 'quadprog'. For non-simulation builds, calls to unsupported MATLAB functions are eliminated if they do not affect function outputs.

Thank you.

Hi,

taking a look at the list of supported functions it looks as if quadprog can not be used for code generation with MATLAB Coder.

Could you give me some advices on how to reliaze the 'quadprog' function in C code?

[Titus Edelhofer]

Writing this from scratch will not be a too simple task. I would try netlib.org or google to find something. Otherwise probably the "Numerical Recipies in C" will contain some code.

I agree with Titus, but if you can share it, I would be very interested to hear more about your application. Are you going to generate code for an embedded system?
