Trouble running glmnet in Matlab R2019b on Mac Os Catalina 10.15

Has anybody else encountered problems using the glmnet package on Mac Os Catalina 10.15? I am using Matlab R2019b.

I downloaded the package and saved all files within my working directory. When I try to invoke the glmnet function, I get the following error:

Invalid MEX-file

'/Users/name/Desktop/glmnet_matlab/glmnetMex.mexmaci64':

dlopen(/Users/name/Desktop/glmnet_matlab/glmnetMex.mexmaci64, 6): no

suitable image found. Did find:

/Users/name/Desktop/glmnet_matlab/glmnetMex.mexmaci64: code

signature in

(/Users/name/Desktop/glmnet_matlab/glmnetMex.mexmaci64) not

valid for use in process using Library Validation: library load

disallowed by system policy

I also get an error if I go into my working folder and try to open up the file in question ( glmnetMex.mexmaci64 ) with Matlab. When I do this, I get a pop-up error window saying

Error using Open. Cannot edit the Mex- file.

Any thoughts on how to get around this? Any help is much appreciated.

Thanks,

Mick

I get the same error when trying to use the matlabPyrTools package (https://www.cns.nyu.edu/~lcv/software.php):

Invalid MEX-file '/Users/name/matlabPyrTools/MEX/corrDn.mexmaci64': dlopen(/Users/name/matlabPyrTools/MEX/corrDn.mexmaci64, 6): no

suitable image found. Did find:

(/Users/name/matlabPyrTools/MEX/corrDn.mexmaci64) not valid for use in process

using Library Validation: library load disallowed by system policy.

I am on Catalina as well, but am using Matlab2018b.

You need to whitelist the executable; https://bugs.launchpad.net/gcc-arm-embedded/+bug/1832620
