MIRtoolbox installation. Cannot use functions

Hi . I have Matlab R2018a on Ubuntu Linux. I've recently downloaded MirToolbox and installed it by moving the main MIRtoolbox folder into the toolbox MATLAB folder.

Then, I've set the path to the folder. When I write the command "help mirtoolbox" it shows me all the functions that I can use.

Then I write the "help miraudio" command and it also shows me what the function can do. But when i actually use the function

( like : miraudio('sound.wav') ) it tells me that the function is undefined. How can i fix this ? :(

‘I've recently downloaded MirToolbox and installed it by moving the main MIRtoolbox folder into the toolbox MATLAB folder.’

You put it in the wrong place.

The MIRToolbox is a File Exchange contribution. You shoiuld copy it to a folder in your MATLAB user path, not the MATLAB toolbox folder.

It would likely be best to create a separate folder for it, then copy it to that folder, and add that folder to your search path. For information on the MATLAB search path, see the documentation section on What Is the MATLAB Search Path?

Yes it worked. Thank you so much. I've copied the MIRToolbox folder to the user path folder, i've set the path and now I can use the function.

Unfortunatelly, now I have another problem. When i use the miraudio fumction and set the path to the file that i want to read, it tells me that MIRREAD can not open file

Nevermind, I've just changed to version 1.7.2 and it worked. Thanks again

As always, my pleasure.
