What is mesh function?
mesh( X , Y , Z ) creates a mesh plot, which is a three-dimensional surface that has solid edge colors and no face colors.
The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y .
mesh( Z , C ) additionally specifies the color of the edges..
What is mesh grid?
meshgrid function is used to create a rectangular grid out of two given one-dimensional arrays representing the Cartesian indexing or Matrix indexing. Meshgrid function is somewhat inspired from MATLAB. … meshgrid function returns two 2-Dimensional arrays representing the X and Y coordinates of all the points.
What is the difference between mesh and surf in Matlab?
Accepted Answer surf() and mesh() both create Chart Surface Objects in current releases. surf() turns on face coloring by default and uses black edges by default, whereas mesh() turns face coloring off by default and uses colored edges by default.

Why do we need mesh?
Finite Element Method reduces the degrees of freedom from infinite to finite with the help of discretization or meshing (nodes and elements). One of the purposes of meshing is to actually make the problem solvable using Finite Element. By meshing, you break up the domain into pieces, each piece representing an element.
