Hello!
I have a small problem and i think it is quiet easy to solve but i struggle.
I've got an array Lock19 = 86371*1 double... this array consists of a lot of -5 and other various random numbers.
My Variable is Lock19 = data(:,7)
now i want to overwrite those numbers ... so every -5 should become 3 and every other number should become 0.
It shouldn't be that hard, I tried it like this:
if(Lock19 == -5)
Lock19 = 3
end
if(Lock19 ~= -5)
Lock19= 0
end
plot etc....
Thanks for your help !!!

Try
Lock19(Lock19~=-5)=0;
Lock19(Lock19==-5)=3;
