Answer 1

[Walter Roberson]

temp = load('z1.mat');
fn = fieldnames(temp);
x1 = temp.(fn{1});

This will load the "first" variable stored in the .mat file into the variable "x1".

yes i know but i need universally code, not for only z1.mat it was only example. Because I work with gui, and I have pushbutton, and around this pushbutton i want to load .mat file :)

[Walter Roberson]

[filename, foldername] = uigetfile('*.mat', 'Select a mat file');
fullname = fullfile(foldername, filename);
temp = load(fullname);
fn = fieldnames(temp);
x1 = temp.(fn{1});

If you know your file will be named data.mat, you don't need uigetfile, simply load will do that for you:

x1 = load('data.mat')

[Dominika]

no my file are different, for example: z1.mat, t.mat and others. And I want to load one subject .mat from file and save from workspace but condition is that z1.mat = x1 in workspace.
