'load' command - loading and using data from a .MAT file

Hi there I would like to load data from a .mat file but retain it's structure. It is a 17x17x17 matrix and at the moment I am simply using the following

load current1.mat

MAT = current1

But there seems to be a problem and I am told there is no such thing as current1 where am I going wrong. Also I need to be careful because some of the commands for loading and using data turn it into a 1x1 array??

I'm quite confused :(

x=load('current1.mat');
MAT=x.current1

If you want to know the variables names in your file

whos('-file','current1.mat')

Unfortunately I get the following error message when typing in your code;

Reference to non-existent field 'current1'.

Error in fftndim9part11partfromauthor (line 5) MAT = x.current1;

check the variables name

whos('-file','current1.mat')

What did you get?

I got the following:

Name Size Bytes Class Attributes

current      17x17x17            78608  double    complex

That means, your variable name is current (not current1). Type

x=load('current1.mat');
MAT=x.current

Thank you! It works fine now! :D
