non zero elements in an array
显示 更早的评论
if a=[1 2 4 5 3 0 0 8 0]
how can i make the elements greater than or equal to 2 as 1 and smaller than two as 0.
so that it become like this:
[0 1 1 1 1 0 0 1 0]

a=[1 2 4 5 3 0 0 8 0];
[idx]=find(a<2);
a(idx)=0;
out=a;
[idx2]=find(out>=2);
out(idx2)=1

a(1)=1 % 1 is < 2
It was asked to find >=2 would be 1 and <2 would be 0

but i got the concept which was required.
Except that this solution still teaches the regrettably popular habit of using find() in situations where it is unnecessary.
a=[1 2 4 5 3 0 0 8 0];
out=a;
out(a<2)=0;
out(a>=2)=1

I'm going to assume you're only dealing in integers here, otherwise the question arises whether values between 1 and 2 should really be preserved.
a = [1.5 1 2 4 5 3 0 0 8 0];
b = max(min(a,1),0)
If values between 1 and 2 should be preserved, then:
c = max(a,0);
c(c>=2) = 1
If a are always integers,
a = [1 2 4 5 3 0 0 8 0];
a=(a>=2)
