Problem 17. Find all elements less than 0 or greater than 10 and replace them with NaN
Given an input vector x, find all elements of x less than 0 or greater than 10 and replace them with NaN.
Example:
Input x = [ 5 17 -20 99 3.4 2 8 -6 ] Output y is [ 5 NaN NaN NaN 3.4 2 8 NaN ]

This is a poorly posed problem. There are no numbers that are both less than zero and greater than 10.
Just had the same thought as James Ross...
Fixed the wording to reflect this. Thanks for the comments.
come on wth is this problem i got wrong when i check my answer is true
Can someone explain this to me?
cleanUp=@(lb,x)interp1([lb 10],[lb 10],x);x=[5 17 -20 99 3.4 2 8 -6];y_correct=[5 NaN NaN NaN 3.4 2 8 NaN];
[isequalwithequalnans(cleanUp(1,x),y_correct),isequalwithequalnans(cleanUp(0,x),y_correct)]
That is, if i set the lower bound (lb) of the interpolation to 1 it passes the test code but if I set it to zero it fails with the same output!?!
The 3.4 in the result isn't the same in the two interpolations (diff= 4.440892098500626e-16). It's small but it's enough to fail the isequal test.
16 is the first non-regexp-solution!
good question
I have Assertion failure for the first test but it's good for the second --' I don't understand. Can you help me ?
More usefull than I thougth
useful basics
hay
cool problem!
goog
good problem to learn!
