every time i start matlab r2018b and run a script i got the message "Octave functions should not run on Matlab, Removing path" and the script fails

second run works fine

Do you have a startup.m file?

[kira]

i don't think so. I installed, setup path folder and that was all my config

[Adam]

What does 'a script' contain?

[kira]

pffff, i have a lot of scripts. They are all different and as far as I tried now, all of them gives this warning. There is also a lot of custom functions. I usually use, DL, Wavelet, Parallel, SP, PDE SandML, toolboxes.

restoredefaultpath;
rehash toolboxcache
savepath

[kira]

ok, but i won't be able to use my paths, isn't?

[Walter Roberson]

If the above works for you, then you can later use pathtool to add on any additional paths you need ... after first checking that they have no startup.m file.
