Define range of values from an array

Question

0 个投票

Dear MatLab comunity,

I got an array (x) of angles ranging from -180 to +180 degrees. I have to define two vectors that include the following values:

Cis = all the values between -90 and 90

Trans = all the values below -90 and above +90

I did the following:

Cis = X((X > -90) & (X < 90));
Trans = (X(X > 90) & X(X < -90));

Problem: the first line (cis) works and the second line (trans) doesn't and gives me an empty set. What's the problem?

Thank you in advance,

Alessandro

Trans = X(X > 90 | X < -90);

Question: which one should include exactly -90 or exactly +90 ?

Thank you! That works fine! No one should include the -90 and/or +90 so I think is fine this way.
