How to load all variables from *.mat except one?

Hi all,
I want to load all variables from a *.mat-file except one. Here are my lines:
X = 10;
if restart == 1
clearvars -except zz X ds_restart delta_t
load(['restart_safety_' num2str(X)], '-regexp', '^(?!delta_t)...');
restart = 0;
end
As far as I understood, this will load all variables from restart_safety_10.mat and write over except those having 'delta_t' in their name. I want to keep 'delta_t' from before and do not want to load it. Unfortunatly, there are further variables ignored named e.g. 'N'. I am sure all variables are in the .mat-file since I can load all variables using only
load(['restart_safety_' num2str(X)])
What is happening here? Why are there more variables ignored? Does anyone know a better way than working with regular expression?
Thanks for your help. Franziska

Use
load(['restart_safety_' num2str(X)], '-regexp', '^(?!delta_t)\w');

As another example, you can load all variables except those which already existed in the workspace:
varlist = who; %Find the variables that already exist
varlist =strjoin(varlist','$|'); %Join into string, separating vars by '|'
load(TSfile,'-regexp', ['^(?!' varlist ')\w']);
