Given a vector v and a element e, return the number of occurrences of e in v.
Note: NaNs are equal and there may be no occurrences of e in v
v = 1:10
e = 2
output = 1
The comment about NaNs being equal is rather vague, clarify or give a specific example
NaN==NaN gives 0 help me
Use isnan keyword. isnan(NaN) gives 1
There should be a test to stop this from passing
This just got lucky on the test suite. It would fail on ecount(1:12,2), for example.
Find all elements less than 0 or greater than 10 and replace them with NaN
