Hi,
I have two folders in the drive as D:/data/folder1, D:/data/folder2.
In folder1, I created a 'M1.m' file which loads different data of different TYPES and length as A, B, C....
Now I want to use data 'A' in my 'M2.m' file in folder2 and I am trying this
load('D:/data/folder1/M1.m') in M2.m but it gives me an error.
Can you help me to know, How can I access data 'A' in M2.m?
Thanks

"All the preceding variables I defined in M2.m lost from the workspace."'
There are multiple reasons why that might happen:
- your code does not pass the required values as input/output arguments.
- your code calls clear.
- you are looking in the wrong workspace.
- That variable is not actually created.
- etc.
If you do not show us the code that you are trying to run we can only make guesses.

I'm going to guess that your m file is not a function but a script. I would recommend using functions for anything but testing. That way you can make your code modular. The function below will execute the script and return the A variable.
function A=getA
%run the script and return the A variable
run('D:/data/folder1/M1.m')
end
You shouldn't use this as a structural solution.
