在 MATLAB Online 中打开

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".

在 MATLAB Online 中打开

[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')
