Replace value that are associated to a location by nan

1 view (last 30 days)
Dear all,
I have a question that I hope you can help me.
I have a map of sound pressure levels (spl) in which I patched a white band using countour command as you may see in this figure.
Brifelly, I used surf(longitude,latitude,SPL_dB) to plot the spl levels and then I used c2=contourf(longitude,latitude,elevation', [100 100],'facecolor',[1 1 1]) to create the white band, where elevation is the bathymetry of the area.
However, now I would like to delete or replace by NaN all the values in my spl matrix that are covered by that white band.
How can I do it?
Thank you very much

spl(0<= elevation & elevation<=100)=nan;
