I want to save variables from a nested function into the parent function workspace so that I can use these variables again in another nested function. How do I do this?

parent function ...
%user input numbers that go into BeamReactions
BeamReactions(BeamLength,BeamMass,Load,LoadX,LoadAngle)
%this is the function that I want to use answers from BeamReactions in
BeamLoadPlot(BeamLength,BeamWeightN,BeamWeightN_X,Load,LoadX,LoadAngle,FA_Y,FB_X,FB_Y)

Don't do that. Instead, inside the parent function but before the definition of either nested function, assign some value to the variables, even if just []. That tells MATLAB that the variable is to be shared.

The whole point of nested functions is that you don't have to pass data as input/output arguments. All you need to do is define those variables in the workspace of the main function, and then all of the nested functions can access them:
function val = mymain()
val = [];
mynest()
function mynest()
val = 2;
end
end
Try calling it and see what the output is.

hello, what exactly do we need to write inside the parentheses? When I write the code like this, I can see the nested variables, but still cannot save them as files.
