Hi
I have been trying to implement a way to stop the pattern search algorithm, if it reaches a specific function value (or r^2 value in our case). It seems like you can't put 'break' inside the function to stop it with specified values.
Is there any particular fucntions that we can use as a stopping function?
Thanks a lot.

You can use an outputfcn for this. The output function can pass back a stop flag.

I was able to stop using the outputfcn. Thanks for your answer and help.

Hard to say with out seeing the code. You can put a break inside a for loop or a while loop and it will go to the line right after the end of that loop with all the values having whatever value they had last.
If you just want to exit the entire function immediately, you can use "return" instead of break.
Post your code if you want more help.

Sorry, when you said "pattern search algorithm", I thought you had your own pattern search function you had written. I didn't know that you were referring to the patternsearch() function that is built in to the Global Optimization Toolbox.
I'll remove the space from the tag, and add the Toolbox to the product list to make it more clear.

I am sorry for making it confusing.
