## How do you plot a 3d axis in Matlab?

plot3( X , Y , Z ) plots coordinates in 3-D space.

1. To plot a set of coordinates connected by line segments, specify X , Y , and Z as vectors of the same length.
2. To plot multiple sets of coordinates on the same set of axes, specify at least one of X , Y , or Z as a matrix and the others as vectors.

## How do I create a mesh plot in Matlab?

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 . The edge colors vary according to the heights specified by Z .

What is the difference between mesh and surf in Matlab?

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.

### How do you make a 3D line in MATLAB?

1. [X,Y,Z] = peaks(100) ;
2. % DRaw a line at origin.
3. x = linspace(-3,3) ;
4. y = repelem(0,1,length(x)) ;
5. z = interp2(X,Y,Z,x,y) ;
6. % plot.
7. surf(X,Y,Z)
8. hold on.

### What is mesh plot?

Definition 12 (Mesh Plot) A plot which depicts a function q(x, y) by plotting a fishnet- shaped lattice of horizontal and vertical lines in three-dimensional space as if the net had been draped over the surface of q. Alternative Names: FISHNET PLOT, WIREFRAME DIAGRAM.

Why mesh plot is used?

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)

## What is contour plot in MATLAB?

contour( Z ) creates a contour plot containing the isolines of matrix Z , where Z contains height values on the x-y plane. MATLABĀ® automatically selects the contour lines to display. The column and row indices of Z are the x and y coordinates in the plane, respectively.
