## How do you plot a 3D graph in 2d in MATLAB?

Direct link to this answer

- % 3D.
- t = linspace(0,10,500);
- xt = exp(-t./10).*sin(5*t);
- yt = exp(-t./10).*cos(5*t);
- patch([xt NaN],[yt NaN],[t NaN],[t NaN],’FaceColor’,’none’,’EdgeColor’,’interp’);
- xlabel(“X”)
- ylabel(“Y”)
- zlabel(“Time”)

## What is MATLAB command for visualization of surface of the given function?

surf( X , Y , Z ) creates a three-dimensional surface plot, which is a three-dimensional surface that has solid edge colors and solid 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 . surf( Z , C ) additionally specifies the surface color.

**How do you plot a 3D matrix?**

Creating a 3D plot in Matplotlib from a 3D numpy array

- Create a new figure or activate an existing figure using figure() method.
- Add an ‘~. axes.
- Create a random data of size=(3, 3, 3).
- Extract x, y, and z data from the 3D array.
- Plot 3D scattered points on the created axis.
- To display the figure, use show() method.

### How do you plot a 3d plot in MATLAB?

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

- To plot a set of coordinates connected by line segments, specify X , Y , and Z as vectors of the same length.
- 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 to use a colormap in MATLAB?

Figure object. The figure colormap affects plots for all axes within the figure.

**How to animate this 3D plot in MATLAB?**

Animate the Surface. To animate the surface, use a for loop to change the data in your plot. To replace the surface data, set the XData, YData, and ZData properties of the surface to new values. To control the speed of the animation, use pause after updating the surface data.

## How to plot single points in MATLAB?

Matlab’s default plotting command, plot (x,y), connects the points created from list x and y with line segments. If you plot enough points, you will get a smooth looking curve, as shown in Figure 4 (b), but if you don’t plot enough points, then plot (x,y) will produce a kinky plot like the one shown in Figure 4 (c).

## How to change line color in MATLAB?

p = plot ( [1 2 3 4 5 6], [0 3 1 6 4 10], ‘-o’, ‘Color’ , [0.5 0 0.8]); Next, change the color of the line to a shade of green by setting the Color property to the hexadecimal color code ‘#00841a’. Then change the line style to dashed, and change the markers to asterisks.
