This function can be called exactly the same as one would call MATLAB's CONTOUR function. It directly calls CONTOUR and then takes the output and converts it into a KML file, so that the contour lines display nicely and natively in Google Earth.
If you want to change the color and/or width of the contour lines, you will have to edit lines 38-40 of the function. There are some comments there to guide you.
KML_CONTOUR(LON,LAT,Z) writes contour lines in the same format as
matlab's CONTOUR(LON,LAT,Z) or CONTOURC(LON,LAT,Z).
KML_CONTOUR(LON,LAT,Z,N) draws N contour lines, overriding the
KML_CONTOUR(LON,LAT,Z,V) draws LENGTH(V) contour lines at the values
specified in the vector V
KML_CONTOUR(LON,LAT,Z,[v v]) computes a single contour at the level v
LON: This can be either a matrix the same size as Z or a vector with
length the same as the number of columns in Z.
LAT: This can be either a matrix the same size as Z or a vector with
length the same as the number of rows in Z.
Z: Matrix of elevations
This function creates a kml file called 'doc.kml' in the current
for anyone interested, I also have a version written in Python available here:
