How can I create my own workspace?
in [Matlab]

Do you need only read access, or read/write access? Is it acceptable to have one or more "accessor" functions that need to be called to get or set the values, or is your expectation that the workspace will be "shared" and that you will be able to access the variables by name, something along the lines of: %FizzBoom is a variable in the nested function import_the_workspace(); %display what FizzBoom is currently in the nested function without %specifically importing it disp(FizzBoom); pause(0.5); %display the updated FizzBoom from the nested function without %specifically asking for it again disp(FizzBoom); %if FizzBoom is a loop counter of an active loop, then if you update its %value, is it important that the loop skip (or go back) to the new value? %Keeping in mind that if you try to assign a new value to a loop counter from %within matlab, that at the beginning of the next loop trip the change in %value would be ignored and the next loop value in normal sequence would be %used -- so do you need access to the *internal* variables to be able to %mess with them? FizzBoom = FizzBoom + 23; You will likely not be able to access the toc() value: the start time is saved by tic to an unnamed location.

Then, if I've understood what you're after, you can use the function below. function StateStruct=wspace(fhandle) %Get the workspace of a function handle % % StateStruct=wspace(fhandle) % %For now, very rudimentary. z=functions(fhandle); StateStruct=z.workspace{1};

I don't want to edit the loop counter, and toc isn't very important actually, but I want to obtain which variables were used and make new variables with the exact same name in my new workspace/function, which have the same values as the previous variables. Also, this needs to be general (no passing on information from one function to another). I think I'm aiming too high but maybe there's something out there? So far my only option is using image processing and some long techniques to read the workspace window and the values inside. |
