MATLAB: ‘load’ command – loading and using data from a .MAT file

loadloading and using datamatretaining array dimensions

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 1×1 array??

I'm quite confused 🙁

Best Answer

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

If you want to know the variables names in your file

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

MATLAB: Hi, i have a .mat file and i have images in that file. i need to view the each image.

The reply "testdata = 1x67 struct array" reveals, that a struct array is replied. So please try:

storedStructure = load(fullMatFileName)
for ii = 1:numel(storedStructure)
  figure;  % Open a new figure
  image(storedStructure(ii).image);
end

MATLAB: Why can’t i Load .mat file? It shows ” cannot read the file”

It's like this one. There are R1 and diff in this file. And i can load diff, but not R1. By the way, "Load" can work with only one variable, like below:

load("filename.mat", "diff")

And what do you mean generating file again? Do you mean that i need to create the file again and abandon the corrupted one?
