How to Draw 3D plots in MATLAB
3D ploting in MATLAB
a) Define a mesh in MATLAB by using the meshgrid function.
b) Use meshgrid function to create 3D plots by using mesh, and surf functions in MATLAB with the help of suitable examples.
[X,Y] = meshgrid(x,y) : It returns 2-D grid coordinates based on the coordinates contained in vectors x and y.
X is a matrix where each row is a copy of x, and Y is a also a matrix where each column is a copy of y.
The grid represented by the coordinates X and Y has length(y) rows and length(x) columns.
mesh(X,Y,Z): It draws a wireframe mesh with color determined by Z, so color is proportional to surface height.
surf(X,Y,Z); It creates a three-dimensional surface plot. The function plots the values in matrix Z as height.
The function also uses Z for the color data, so color is proportional to height.
