How to permanently change the temp directory matlab uses?

I saw the following in another post for changing the temp directory. However I believe everytime Matlab restarts the TEMP directory is reset to the c:\temp folder.

     tempdir 
     clear all
     setenv('TEMP','NEW_DIRECTORY_PATH') % TEMP for Windows
     tempdir

I am running out of space in C:. I should move the temp folder permanently to another drive. Can anyone give me a suggestion? Thanks

This does not work for me. when I use setenv(), the ouput of tempdir is unchanged. I have tried this on my desktop using Matlab and I am also trying to use this on a linux cluster, so changing admin rights etc is not really an option.

K>> tempdir

ans =

    'C:\Users\bs11t2r\AppData\Local\Temp\'

K>> setenv('TEMP', 'C:\Somewhereelse\') K>> tempdir

ans =

    'C:\Users\bs11t2r\AppData\Local\Temp\'

Look into tempdir:

type tempdir.m

Does it store the folder name persistently to save time? If so:

setenv('TEMP', 'C:\Somewhereelse\')
clear('tempdir');
tempdir

Try to use 'TMP' or 'tmp' instead of 'TEMP', I am using a Linux cluster too and it worked for me. The code became:

     tempdir 
     clear all
     setenv('TMP','NEW_DIRECTORY_PATH') % TEMP for Windows
     tempdir

Thanks Lucas!!!

>> clear('tempdir')
>> setenv('tmp','D:\Matlab_temp\')

then type

>> tempdir

Matlab Yields

ans =

    'D:\Matlab_temp\'

This is implemented in 2019b version
