Save all workspace within a function
显示 更早的评论
Hello everybody! I'm trying to save the all workspace using the function save within a function. Unfortunately, if I do that, it saves only the local variables of the function, while I would like to save the global workspace. Is there a way to do that, which is not declare all variables as global variables?
Thank you!

Why can't you just save the workspace variables from the workspace? One of the key points of a function is that it has its own scope and isn't contaminated by all the variables outside it.

I see you accepted Geoff's answer so I assume that achieved what you want, although the exact nature of what you are aiming for still seems a little unclear. As far as I understand it, using that approach will save the workspace variables to file, but those workspace variables will be exactly the same as they were at the point you called the function unless you are using OOP with handle-derived classes or doing some ghastly assignin type behaviour within your function.
I would have thought that the progress which you mention would be encapsulated within your function, not in the base workspace.

Baham91 - if it is absolutely necessary to save the variables from the base workspace from within your function, then you can use the evalin function to do so. For example, you would do
evalin('base','save baseVars.mat');
which will evaluate the command
save baseVars.mat
in the base workspace, and so will save all variables from there into the file baseVars.mat.
There is some concern about using this function, so be wary and only use it if you are convinced that you need to do so.
