Mesh Surface Plot in MATLAB

Mesh Surface Plot is used to depict f(X, Y, Z) in a three-dimensional space. Matlab allows users to create mesh surface plots using the mesh() method.

Different syntax of mesh() method are:

• Mesh(X, Y, Z)
• Mesh(Z)
• Mesh(___,C)
• Mesh(___, Name, Value)
• S = mesh()
• Mesh(ax,____)

Mesh(X, Y, Z)

• It plots X, Y, Z on a three-dimensional surface.
• Matrices X, Y are plotted along the x-y plane and plots matrix Z as height above the x-y plane.
• If size(Z) = [m, n], then X should be of the same size as Z or a vector of size n.
• Y should be the same size as Z or a vector of size m.

Example:

Output :

Mesh(Z)

It creates a mesh surface plot with matrix Z by considering column and row indices as x and y-coordinates respectively.

Example:

Output :

Mesh(___, C)

• It creates a mesh surface plot with the specified color of edges as C.
• C is an m-by-n-by-3 of RGB array where Z is a matrix of size m-by-n.

Example:

Output :

Mesh(___, Name, Value)

• It creates a mesh surface plot with the specified Name-Value pair arguments.
• Some properties are Face Alpha, Edge Color, Line Style etc.

Example:

Output :

S = mesh(___)

• It creates a mesh plot with specified variables and returns the chart surface objects of the mesh plot.
• You can modify the mesh plot even after creating the plot using the variables.

Example 1:

Output :

Properties of mesh plot :

Example 2:

Output :

Mesh(ax,______)

This function is used to specify axes in the mesh plot instead of current axes.

Output:
