Hi all,
i have a small problem i generated an import function for the matfiles i have. When i run the function seperatly every thing is fine but i want that the function import the data when i run the main code
function importfile(Monate,Uhrzeit)
%IMPORTFILE(FILETOREAD1)
% Imports data from the specified file
% FILETOREAD1: file to read
% Auto-generated by MATLAB on 27-Nov-2016 20:49:08
% Import the file
newData1 = load('-mat', 'Monate.mat');
% Create new variables in the base workspace from those fields.
vars = fieldnames(newData1);
for i = 1:length(vars)
assignin('base', vars{i}, newData1.(vars{i}));
end
% Import the file
newData2 = load('-mat', 'Uhrzeit.mat');
% Create new variables in the base workspace from those fields.
vars = fieldnames(newData2);
for i = 1:length(vars)
assignin('base', vars{i}, newData2.(vars{i}));
end

Your function is ignoring the inputs ? Should the inputs be the two file names to import?

That code imports data into the base workspace. If you invoke this from a different function, you would need to fetch the result from the base workspace.
However, this code "poofs" variables into existence in the base workspace, and you are asking to instead have the variables poofed into existence in the function you are running. That is not a good idea. You should instead skip the function and use
monate_struct = load('Monate.mat');
uhrzeit_struct = load('Uhrzeit.mat');
and then reference fields of monate_struct and uhrzeit_struct . This is safer, more efficient, and easier to debug.

load() always loads into the current workspace. If you are inside a function then it is the workspace of the function, and the values will disappear when the function returns unless you save the values.

Thank you for your big help. I have done everything without your last tip (just changed the position of some variables). It seems not so good but for the first result the programm do what it should do. Now i will work on it to make a clean code! A Big THANKS!
