Cant find function from downloaded toolbox

Hello,

I am using a MacBookPro M1-chip computer, and Im curerntly running MatLab 2020b. Throguh a school project I have to use functions from two toolboxes, downloaded through these links. The codes in the folders are written in matlab apperantly. When i Unzip and put them in a folder, witch i "add to path" and then try to run one of the function i get the error "Undefined function 'Funtion_name' for type double"....

Toolboxes

• https://www.kevinsheppard.com/code/matlab/mfe-toolbox/
• The other toolbox is from my teacher, but same problem occor

Some info: (note that the toolbox MFE is appreantly installed, but are not working..)

Is this a problem that somebody can help with?

Please give an example of a command that fails.

[Andreas Bull]

[adfstat, pval, critval, ~, lags_level] = augdfautolag(ret.GSPC, model, maxlag, ic);

where...

 class(ret.GSPC)

ans =

    'double'

    % and the other input are...
model  = 2;
maxlag = 12;
ic     = 'BIC';

returns error:

Unrecognized function or variable 'augdfautolag'.

Error in Assignment_2 (line 96)
[adfstat, pval, critval, ~, lags_level] = augdfautolag(ret.GSPC, model, maxlag, ic);

Did you run the addToPath function provided with the toolbox? It is needed to put the sub-directories into the path.

[Andreas Bull]

Thank you! That must have been the issue for the first package! Thank you! However I don´t have a "addtoPath" code for the next toolbox.. How can I solve this? I am a bit scared to do something wrong here.

The other toolbox is from your teacher, you indicated. I have no idea what code it has, or what command you are using to invoke it.

[John D'Errico]

I wonder if it was installed inside the MATLAB toolbox heirarchy of folders. And that will generally be a bad thing, because MATLAB caches those folders. So when you added it to the path, MATLAB did not recache that directory.
