I am trying to add some features to a 515 line script my boss wrote. I'm fairly new to Matlab, but I have figured out what I want to do--I just need to understand the variables he is using. (I'm trying to add standard error to a linear fit, using polyfitn).

For example, in this line of code on line 373:

[Fit_coeffsAve, S] = polyfit(DdateSR_rel, mean(RatioSR), 1);

I would like to see what values are in Fit_coeffsAve. And of course, once the script runs, the functions do not save data in the workspace. I've tried making that variable global--the entire script runs perfectly, but nothing is saved in the workspace. Thanks for any help you can provide!

Once you have done a Matlab tutorial you should understand why that is an inefficient method. And you should really re-read the documentation for global and never use it again until you do understand in.

@Kelly Cox: rather than using evil GLOBAL variables, this is a good opportunity to start learning how to set a breakpoint to stop the code on/after that line. Then you can simply look at the variable, save it, print its values, etc.
