Hello
I need code VB6 to do work in algebraic expressions until 3 variables.
The user writes in the text box the following function f(x1,x2):
5x1^3 + (x1^2+x2^2)^2 + 3*x1*x2^2 - 2*x1*x2 and a guess: x1=1 and x2=2 (example).
I need to show the expressions of the partial derivatives and to compute their value in this guess.
I need code to get the expression simplified as a monovariable function of "t" after the substituion (example) x1=1+4t and x2=2-3t.
After that I can go on with the computations (method Frank-Wolfe) to optimize nonlinear functions in convex spaces.
Of course I'm ready to pay the code.
Best regards
