I am using GA toolbox...i now need to plot a graph which will show one of the parameter values for each iteration vs no. Iterations...can anyone help me out??

Use a plot function. If none of the built-in functions are suitable, then write a custom plot function in the appropriate syntax.

I want to use one of the parameters that i am using can you show me how can i write such function?? An example code might help...pls

Sorry, I should have said before that you can just edit one of the existing plot functions such as gaplotbestindiv or gaplotbestf, save it with a different name, and use it as a plot function.

Remember, ga has a population, so at each iteration (generation) there are many individuals. You will have to decide which, if any, to plot.

Good luck,
