How to import randomly named files from a folder into different matrices

Hi,

I have the same problem as stated here https://se.mathworks.com/matlabcentral/answers/1810-opening-files-with-randomly-varying-file-names, but the problem is to go further from Olegs answer. Once I have the matrix called names, how to I add the matrix content into a path directory ( for example like

Matrix = fopen('C:\Users\Oleg\Desktop\Nuova cartella\names(1)');

where names(1) should be transfered into the name of the file currently in names(1).

What exactly is a "path directory" and what does it mean to "...add the matrix content into a path directory" ?

The sentence "...where names(1) should be transfered into the name of the file currently in names(1)" is unclear: can you provide an example of what you are trying to achieve? Are you trying to rename files?

If I understand correctly, try

filename=strcat('c:\Users\Oleg\Desktop\Nuevo cartella\',names(1,:));
matrix=fopen(filename);

Of course, they can be combined into one line.

Hope this is what you are after.

Most likely names is not a char matrix. Then, if it is a cell string:

filename=strcat('c:\Users\Oleg\Desktop\Nuevo cartella\', names{1});

Remember, that strcat removes leading spaces smartly. Although leading spaces are a bad idea for file names, this would be safer:

filename = ['c:\Users\Oleg\Desktop\Nuevo cartella\', names{1}];

[EDITED, after Stephen's comment] And even better, because it cares for the path separators:

filename = fullfile('c:\Users\Oleg\Desktop\Nuevo cartella\', names{1});

[Stephen Cobeldick]

It is recommended to use fullfile rather than concatenating strings together.
