Loading Parameters from Text File into Function

I would like to us a .m text file to load parameters into a function. In my real example I have many parameters so I'd like to avoid needing to type them into the function call, I'd rather load them from a txt file. For example:

parameters.m

a=1;
b=2;
c=3;

Then I want to do something like this

function result=myfunc()
  load parameters.m
  result = a+b+c
end

The only solution I've found is to first run parameters.m as a script, save the workspace variables to a .mat file and then load the matfile, but this is very round about and wastes space by creating the .mat file. Are there other solutions?

This sounds like a The XY Problem

Try replace

load parameters.m

by

parameters

or maybe better by

run( 'parameters' )

However, ...

I see your point about the XY problem, should I edit my question or post a new one?
