Hi fellows,
I am using fmincon to find the minimum of function f. Sometimes it gets a value of f is NaN , so fmincon fails to converge. Do you know how to find what value that fmincon is trying when it gets f as NaN?

At the command prompt give the command
dbstop if infnan
and run. When it stops you can examine the parameters passed in to your function.

Look at
whos
and look at the parameter names you gave when you wrote the function and ask to look at those parameters. "x" is pretty common for this purpose.
