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;
