MATLAB: Load() into workspace

load function script

If I place load() into a m-file script, it will load into the workspace, available for the caller.

If I place it into a m-file function, I will have to pass the variable names or nest out the struct.

Is there any way to pass load() into a function and pass whatever is in it directly into the workspace, without doing a lott of messy code?

Why don't you use textread or textscan or fscanf?

doc textread
doc textscan
doc fscanf

You can control the type of variables and furthermore you can even read the data with different delimiters.

OK, got it:

ws = load('workspace6.mat');
map2 = ws.map;
strg2 = ws.strg;

Calling load() without catching the output has such side-effects, when a variable stored inside the MAT-file overwrites a locally used variable from the code:

a = 1;
data = rand(5);
save('test.mat');
a = 17;
load('test.mat');
disp(a)   %  1 !!!

Therefore it is a good programming pattern to catch the output:

FileData = load(fileName);
tempfile = [FileData.data(:,[1 2 3 7])];

Using ls('*exp.mat') to get a list of file names is very indirect. because it converts the output of dir to a CHAR-Matrix padded with spaces. Better:

fileDir  = dir(*exp.mat');
fileName = {fileDir.name};
