"Make" with NaNs instead of zeros

Hi! This is my first forum post, I hope I am following etiquette. I think/hope that I have a fairly simple question to answer, and appreciate any help in advance!

I am using the following line:
make/o/N=(dimsize(wave1,0),dimsize(wave2,0)) New_matrix

to make a matrix with the the number of rows being equal to the length of wave1, and the number of columns being equal to the length of wave2. I get a big matrix with the correct dimensions, and a bunch of zeros. Is there any way I can make this same dimensioned matrix using the "make" command, but have the matrix be filled with NaNs instead? The only way I know how to fix my problem is a manual solution with for loops, which is too cumbersome for this particular piece of code.

Thanks! Sincerely,
Ellis
In case the previous response wasn't a revelation for you, the code could also have be written

make/o/N=(dimsize(wave1,0),dimsize(wave2,0)) New_matrix
New_matrix = nan


That is, Igor will handle a wide range of wave assignments so you don't have to mess with loops. Enter

displayhelptopic "Waveform arithmetic and assignment"

in the command line for more information.
