how to return only true statements
显示 更早的评论
for example, if I have:
>> e=[1 -7 -1.2 6 -9 19 1.8]
and I want matlab to give me only the true statements for e>0
as in:
e=[1 6 19 1.8]
I tried
>> if e>0 e end
but doesn't do anything.
thanks

I think you should read the basics of programming. (not necessary Matlab)
if e>0
e
end
What are you expecting when you write
e

You mean like this
out = e(e>0)

Just do
e>0
You get the following
1 0 0 1 0 1 1
If you want to return the elements
X = e(e>0);
