There is a function Q(t)= a1*A(t)+ a2*B(t)+ a3*A(t)^2*B(t)+ a4*A(t)*B(t) ^2+a5* B(t) ^3+ a6 A(t) ^3+ a7*A(t) ^2*C(t) Where P(t), A(t), B(t) and C(t) are known for any point of time or a sample of time. Then I want to obtain the value of a1, a2, a3,a4,a5,a6,a7 with constrained a1>0, a2<0, a3>0,a4>0, a6>0, a5 and a7 unbounded So that P(t)-Q(t) become minimum or negligible at any point of time.

For anybody stumbling across this, there is the "fminsearch" function, which could be used to do this.
This function is within the default MatLab package.
