How can one write a program to do this? (fminbnd)
显示 更早的评论
I define a function
function out = test(x)
y=x^2;
z=y+1;
out=z
end
Then I run
fminbnd(@(x) test(x),0,1)
This will return the value of x that maxes test(x). But I also want to output y at that optimal. How can one do this?

You can get the value of out = z simply by asking for it:
[xbest,out] = fminbnd(@(x) test(x),0,1)

I am not sure what you want. You can calculate y separately in a function. Your function does not output y.

Define your test function to return two outputs, out and y. fminbnd will only ever call your function with one output. After fminbnd returns the "best x" call test with that best x as the input and two outputs.
