Hello,
I just want to do any easy optimization with matlab, but i need a tip how to do it.
Here is the question:
I have 3 different parameters (a,b,c) which are effecting the result and one result (d). I need to minimize the result by changing the paramaters. How can i do it matlab?
Example:
a=50 b=100 c= 90 -----> d=45
a=80 b=70 c= 60 -----> d=23
a=20 b=65 c= 40 -----> d=58
a=30 b=134 c= 93 -----> d=71
a=40 b=150 c= 36 -----> d=62
a=54 b=100 c= 24 -----> d=25
a=? b=? c=? -------> Min(d) ?
Iam also not good at choosing optimization method, any help about it will be very appriciated.
thank you

I already answered your question here

Why did you repost? In any case, did you try FMINSEARCH? Do you have the Optimization Toolbox? What does d(a,b,c) look like as a function?
