How to open a .mat file in Matlab

Hi,

I'm trying to open a .mat file in Matlab, but am unble to do it. I followed the instructions from this link below,

http://www.mathworks.com/matlabcentral/answers/103000-why-have-all-my-mat-files-become-associated-with-microsoft-access

After step 6, I have a separate folder for 'R2012B', now what should I select from this folder.Please let me know your suggestions.

How about using the load command? Does that not work?

 load mymat.mat

[Mischa Kim]

The file needs to be in a folder which is on the MATLAB path, or, in the current folder. You can set both in the MATLAB UI.

a=load("1.mat") imshow(a) this is the shortest possible way, and 1 is the name of the image. you will type according to your .mat file.

Spcify the full path of your file

folder = 'c:\whatever........';  % You specify this!
fullMatFileName = fullfile(folder,  'wheel_rail_AW.mat')
if ~exist(fullMatFileName, 'file')
  message = sprintf('%s does not exist', fullMatFileName);
  uiwait(warndlg(message));
else
  s = load(fullMatFileName);
end

Thank you.

I just got a more user-friendly way of selecting a *.mat file, so thought to share:

[fileName,filePath] = uigetfile('*', 'Select data file', '.');

if filePath==0, error('None selected!');

end

U = load( fullfile(filePath,fileName) );

enjoy!!

use :

whos -file fileName.mat

fileName.mat should be in matlab path

That could tell you which variables are in the file, but does not load the data from the file.
