Would somebody help me please in this question. I'm new in Matlab... And it's a bit hard for me to understand how to create and use genetic algorithm in Matlab. If anybody could help to write some very simple code for searching minimum/maximum of specified function. I read that the gatool should be used for that... but I can't understand the examples of Matlab help network. I'm doing the next steps:Would somebody help me please in this question.
