## Main Question or Discussion Point

**1. Homework Statement**

Hi all! I'm trying to solve the following problem but I'm not too sure of a few things.

Write Matlab instructions to plot a three dimensional Gaussian:

A = A0exp((x^2 + y^2 + z^2)/w^2)

choosing appropriate values for A0,w and range of coordinates.

**2. Homework Equations**

I'm guessing i have to use the plot3 command but after that I'm lost

**3. The Attempt at a Solution**

I dont know how to choose appropriate values for all of the variables.And what is w?

I'm a bit lost so I'd really appreciate any hints or tips to point me in the right direction thanks debs
