2 % PCOLORFV(X,Z,H,A)
3 %
4 % Is the same as PCOLORFV except it automatically extends the dataset
5 % to the depth of the topography "H". This is srictly for plotting
6 % vertical (x,z) sections in conjuction with "partial cells" in the MITgcm.
7 %
8 % X is horizontal coordinate (vector)
9 % Z is vertical coordinate (vector)
10 % H is depth of bottom (vector)
11 % A is field to be plotted (matrix)
12 %
13 % Optional arguments are passed on to PCOLOR
