Setting an array of a vector = NaN

9 views (last 30 days)
Dear Matlab community,
I am trying to set a certain array within a vector = NaN
Example:
If I have a vector with a dimension 9,1:
0.0001
0.0003
0.0001
0.0002
2
3
4
5
6
And I would like to set the elements 1-4 = NaN, to get the following output:
NaN
NaN
NaN
NaN
2
3
4
5
6
Does someone know how to set an array within the vector to NaNs? In this case, I know that element 1-4 should be NaNs.
Thank you very much!
Chris

This will do what you want:
V = [0.0001
0.0003
0.0001
0.0002
2
3
4
5
6];
V(V<1) = NaN

My pleasure.
I thought you wanted to set specific conditions on what elements became NaN.
