To plot simple functions in MATLAB, follow these steps: 1. First, define the independent variable x and set the domain for x; 2. Then define the function y, y = f(x); 3. Finally, call the plotting command, such as the plot command: plot(x,y), where x represents the X coordinate values and y represents the Y … Read more
Below we present some function curves or surface plots drawn using Matlab. Since the public account cannot process EPS images, the images we screenshot are all bitmap, so you will see the ‘jagged edges’. To appreciate high-quality images with smooth edges and no jaggedness when zoomed in, please click on “Read the Original (Extraction Code: … Read more

1. Two-Dimensional Data Curve Plotting 1.1 Basic Function for Drawing 2D Curves The plot() function is used to draw linear coordinate curves on a two-dimensional plane. It requires a set of x coordinates and corresponding y coordinates to plot a 2D curve with x and y as the horizontal and vertical axes, respectively. Example: t=0:0.1:2*pi; … Read more
1. Bar Plot t = -10:1:10; subplot(2,2,1); bar(t, cos(t)); Copy code This creates a vector t containing elements from -10 to 10. In the first subplot, the bar function is used to plot the bar graph of cos(t). The first parameter of the bar function is the x-axis coordinates, and the second parameter is the … Read more
