Hi,
I have two cell matrices with same dimensions (63,820)
for each cell of Matrix AA there is a corresponding numeric value in same location cell of Matrix BB. However, there are many instances where Matrix BB has NaN values.
I wish to have a Matrix CC which should be exactly same as Matrix AA but it should replace/swap its cell's contents to 'NaN' if the corresponding value of the same location cell in BB is a NaN.
Any body with a short code?
All help will be appreciated.
Regards,
AMD.

AA={1 2 3;4 5 6;7 8 9}
BB={10 nan 2;nan 5 55;nan 44 66}
CC=AA
CC(cellfun(@isnan,BB))={nan}
