Hi everyone,

I need to input the name of a file, or input the path into a function to load that file. However, that file has to be retrieved from a directory that is not in the current directory. I tried to use
addpath('.....'), but putting addpath under the first function line, it doesn't work; MATLAB will just output the error 'no such file or directory' to the input file name.

Does anyone know how I can make something like this:
function loadFile(filename)

%filename becomes a variable to be loaded, and used in the rest of the code



Thanks so much!
Sorry if this seems stupid but I really tried to do a lot of research on this but couldn't figure it out!

doc uigetfile % may be of interest

doc fullfile % and friends...

Here's how I'd do it:

folder = 'C:\Program Files\MATLAB\R2010a\toolbox\images\imdemos';
if ~exist(folder, 'dir')
folder = pwd;
end
filePattern = [folder, '\*.*'];
% Browse for the image file.
[baseFileName, folder] = uigetfile(filePattern, 'Specify an image
file');
if folder == 0
msgbox('You canceled out');
else
fullImageFileName = fullfile(folder, baseFileName);
msgbox (['You selected ', fullImageFileName]);
imageArray = imread(fullImageFileName );
end
