code:

Rep_veh = rand((randi(20)),1);  % random vehicle 20 or x experience scor between 0 to 1 
Spec_veh = (1 + rand(randi(3),1))/2;  % random vehicle  x experience scor between 0 to 1 
Wanted1 = Rep_veh(Rep_veh > .5);
m1=mean(Spec_veh);
m2=mean(Wanted1);
 mean(m1+m2)/2
 

error:

 Array indices must be positive integers or logical values.

Error in two (line 9)
m1=mean(Spec_veh);
 
9   m1=mean(Spec_veh);

Delete the variable you've created named mean that is preventing MATLAB Online from calling the mean function. You should also modify your code so it doesn't create a variable named mean when you execute it.

You could use this command:

exit

This will give a prompt to restart matlab online.

Just click and it should restart.
