Multiplying Double and a Logical

Hello all. This is my first post and this may be a silly question, but I googled the shit out of this to no avail...

I have an array with some NaNs (which is a double), the array is also, therefore, a double). I'd like to (point-wise-.*) multiply this with another array (equal dimension) that is a logical.

I don't mind changing classes of anything. I'm just frustrated not knowing how to deal with NaNs, they're helpful because I have data to plot and NaNs don't give an error if data doesn't quite match up.

Essentially I'm trying to plot something like [ 1 2 3 NaN] with [ 1 3 5 7] (as crude examples). When plotting I'd only get three points (exactly as I want). But I'm making a 'cut' in the data by multiplying a logical (the cut-composed of 1's and 0's) and a double (the actual data containing some NaNs).

I appreciate any help you have!
