I'm trying to make Constant Block in Simulink to take a vector of input that are variables. I plan to use fmincon and the variables a,b,c will be updated as the fmincon executes minimization.
I need to find a way to make constant block take these variables as vector and the output vector will go into another box.
Right now, I have something like this in my m file,
qq=[a b c]; set_param([simfilename '/qq'],'Value',num2str(qq));
I defined the name of the constant block to be 'qq'. This works if qq was single variable say qq=[a]. However, it doesn't work when qq is a vector. If anybody knows what I have done wrong, please let me know! Thank you.

instead of putting qq =[a b c] in constant block update the constant value as [ a b c ]
