How to display every parameter value at every iteration while using Genetic algorithm

Hello,
I am using GA to solve for 6 parameters. I need to define constraints on this parameter like a>b, which I have done. However, I would like to define a stopping criteria for the fitness function. Not sure how to do that.
Most importantly, how can I look at the parameter values at every iteration of GA. I can use display or iter but it doesn't necessarily display the parameter values.
Thank you

You can't just dump them out of the objective function in the command window?
No, it only displays the best value of the objective function but not the parameter values.

Use an Output Function to report whatever you like, and/or to stop the algorithm's iterations when you like.

Also, the parameter values can be simply displayed using [x,fval,output, scores,population,best]=ga[@fitnessfunction,....]
