Creating a surface plot in Matlab

[Abhishek Najbile]

Hi Guys,

I need a little help in creating surface plot for my calculated implied volatility. My strike prices are from 81 to 120 and maturity from 0.1 to 2. How can I plot the volatilities against these? I will really appreciate your help.

Use the fuction meshgrid() to setup the grid, and then use the function mesh() to plot the values.

Alternatively, you can try the function surf() to get a colored 3-D plot.
