MATLAB: Load function sometimes alters structure name in the Workspace

load workspace structureMATLAB

I am encountering a weird phenomena where using the load('filename') function to load a structure, alters the structure name in the workspace. This does not occur everytime, but I observed it on multiple occasions:

Example:

close all
clear variables
load('TM24_w')

results in a structure in my workspace named: "TM242_w"

It does load in the correct structure with the correct fields and values but the workspace name is wrong.

Has anyone ever encountered this and is there a solution?

When you load a mat file without output on the load command, the variable names will be the same as the names inside the mat and not what the file name happens to be.

Using load() returns a structure where all the variables inside the mat file are fields of this structure. You can extract them into their own variable if you want.

% Create mat file with two variables in the single mat file.
save(filename, 'myVar', 'otherVar');
% Show workspace panel:
workspace
% Get rid of them so we can test the recall
clear('myVar', 'otherVar');
% Recall it.
storedStructure = load(filename)
myVar = storedStructure.myVar;
otherVar = storedStructure.otherVar;
