Simple,
I have some personal constants define in startup.m but every time I type CLEAR in the command window I loose them.
Is there a way to make some constants non deletable ?
Thank you.

You could make the constants the Constant properties of a class. Then they can be reused even after issuing clear
classdef myconst
properties (Constant)
a=1;b=2;c=3
end
end
>> myconst.a
ans =
1
>> clear
>> myconst.b
ans =
2

You can use this command
clearvars -except VariblesNotToBeDeleted
