### 3D Plot Part 2 - working with Matlab

1. The ability to handle surfaces and grids is one of Matlab's many strengths. Since a lot of geologic data is naturally of more than one dimension, we have use for these capabilities. The 'o' parameter plots the data points as individual circles as opposed to a 3D-line. The p_h is called a handle
2. MATLAB can plot a 1 x n vector versus an n x 1 vector, or a 1 x n vector versus a 2 x n matrix (you will generate two lines), as long as n is the same for both vectors. The color, point marker, and line style can be changed on a plot by adding a third parameter (in single quotes) to the plot command

The wind data set is an example of vector volume data that represents air currents over North America. You can load this data in the MATLAB® workspace with the command first I create the grid: (since my measurements vectors have more than 400000 samples, do I have to use more than 1000 for x_plot and y_plot to have a good plot? I have also a problem when I increase too much the length of x_plot and y_plot, infact I get an out of memory error message)

### meshgrid (MATLAB Functions

Matlab has a number of methods for interpolating data, both for data that is sampled on a regular grid and for data that is scattered, or Generally I recommend avoiding 3D plots, so in 2D (view(2)): The variables x and y are 10×10 matrices defined by (the equivalent of) [x,y]=meshgrid(linspace(-3,3,10).. By a grid, I assume you mean a matrix. In order to resize a matrix with averaging, you might consider using the imresize function from the image processing toolbox. You need to specify the appropriate interpolation kernel to achive averaging
