MATLAB: How to ignore nan values in using trapz function

nannumerical integrationtrapz

Hello.. I have two column matrix one is height another one is data, both are of same sizes. But both includes some NaN values.
height=[NaN;NaN;NaN;0.246;1.252;2.253;3.2470;4.228;5.192;6.139;7.072];
data=[NaN;NaN;NaN;NaN;NaN;0.0014428;0.0018342;0.0019822;0.0017613;0.0013172;NaN];
I want to integrate the data with respect to height, but as expected it gives NaN output, as the data contains NaN values. Actually the number of NaN is varying for different sets. So can anyone help in general way to omit this NaN element in using trapz function (just like nanmean, nansum, nanstd etc). Extrapolation will give error in my case, so I need answer without extrapolation. Any answer will be helpful. Thanks in advance

Before evaluation, you can get rid of nans as follows:
height=height(~isnan(height))
data=data(~isnan(data))
