有些函数Matlab没有对应的函数:

• pswiggle: to plot anomalies along a track, e.g. altimeter signals along the track, or waterfall plots of temperature and salinity profiles
• makecpt: to make a colormap
• ps2raster: convert your *.ps file into another file format (e.g. *.png)
• pscoast: Plots coastlines with options to shade the land or outline the coasts, and/or add rivers. Probably has an m_map equivalent.
