MATLAB: How to inspect local variables of a function

variables

I'd like to be able to view the local variables generated during the run of a function. One way is to load them to my workspace by saving them to a file, but that could become cumbersome as the number of temporary files proliferate as I experiment with running the function with different parameters. Is there another way?

Use breakpoints either in your script and/or in your function.

MATLAB: What is the best way to use the same constants in different functions

Write a function with no inputs that sets all of your constants in a structure, and return that structure. (Using structures because you said you didn't want it to look bad when you had 50 in/outputs.)

Function like this:

[data] = function your_function()
data.const1 = 12
data.const2 = 23
data.const3 = 2334
data.const4 = '1337'
data.const5 = 10000
...etc etc

Then when you need those constants in your code, call the function like this:

data = your_function

Your constants should be loaded in as a structure, when you need constant one, it will be loaded as data.const1

As far as I know, and I could be wrong, you can't really avoid not having the structure name out front, but you can change it to whatever you want.

MATLAB: How to see global variable in workspace

You need to declare it before you need to use it inside the function where you need to use it.

It looks like p is in your workspace but that might be a different p. Did you use or create a p before you called the global line? The warnings you see tell you that if you use global, it should be the first line in your function. So somehow I think your p is not the global one you thought, but is instead a local p. Is your global p a table or cell array. What does this show:

whos p

Are you stopped at a breakpoint? I think that workspace is not the one corresponding to the code. For example in your code is a variable SoilTypeState but that does not show up in your workspace panel so the workspace panel doesn't seem like it corresponds to the code you are showing, so that's why I think maybe you're stopped at a breakpoint in a different function and then just scrolled down past that to line 325.
