在 MATLAB Online 中打开

Use cell arrays:

 variable{1} = 4;
 variable{2} = 'String';
 variable{3} = 'D:\filehere\hi.wmv';
 variable{4} = yourloadfunction('D:\filehere\hi.wmv'); %replace "yourloadfunction" with a file reading function you know and trust.

Alternatively, use a structure:

 My_structure.Integer = 4;
 My_structure.String = 'String';
 My_structure.filename = 'D:\filehere\hi.wmv';
 My_structure.file  = yourloadfunction('D:\filehere\hi.wmv');

You can also use arrays of structures:
