storedStructure = load('1.mat')
Error using load
Unable to read MAT-file C:\Users\Mark\Documents\MATLAB\work\Tests\1.mat. Not a binary MAT-file. Try load -ASCII to read as text.
Error in test5 (line 1)
storedStructure = load('1.mat')
storedStructure = load('1.mat', '-ASCII')
Error using load
Unknown text on line number 1 of ASCII file 1.mat
"MATLAB".
Error in test5 (line 1)
storedStructure = load('1.mat', '-ASCII')
Looks like it's really corrrupted. Where did you get it or how was it created?

i'm computing sift descriptor values over my dataset. The code works fine and .mat file is being created for each image but values are not showing I'm getting this file as output

But what do you mean by values are not showing. Is the 1.mat file invalid?

Hi,
Try this:
fid = fopen('1.mat');
values = fread(fid);
fclose(fid);
It seems only file created
'MATLAB 5.0 MAT-file, Platform: PCWIN64, Created on: Thu Jan 01 02:47:51 2015'
The rest of data can not be seen.

I'm able to read the data, my 1st coloumn is providing me values. But I have a large dataset and for each img a seperate mat file have to be created. And have to be save in a directory,
But problem is whenever I save file it is not showing data/values.
