![]() Next, we will be creating the circle inside the image. = meshgrid(1 : imageSizeOfX, 1 : imageSizeOfY) Ģ.For this, we will define center, diameter and the image size. First, we will be creating logical image of circle. Next, let us learn how to create a solid 2D circle in MATLAB:ġ. How to Create a Solid 2D Circle in MATLAB? Plot(CenterX, CenterY, 'k+', 'LineWidth', 3, 'MarkerSize', 14) Īs we can see in the above output, the circle is created with a radius 20 and centre (50, 40) as defined by us in the code. This is how our input and output will look like in MATLAB console: plot(CenterX, CenterY, ‘k+’, ‘LineWidth’, 3, ‘MarkerSize’, 14) ĥ.This is normal formatting and we can adjust it as per our requirement. We will also write some code for our output to look visually better. The centre will be defined by x and y co-ordinates.Ĥ. Let us now declare the radius and centre of the circle. The below code will create these points.Ģ. Let us first declare some points, here we are taking 500 points. Plot(x,y), xlabel('x'),ylabel('exp(–1.Hadoop, Data Science, Statistics & othersġ. Following example demonstrates the concept − Example Where, m and n are the number of rows and columns of the plot array and p specifies where to put a particular plot.Įach plot created with the subplot command can have its own characteristics. ![]() The subplot command is used for creating subplots. When you create an array of plots in the same figure, each of these plots is called a subplot. When you run the file, MATLAB generates the following graph − Generating Sub-Plots The following example shows this − Example You can provide minimum and maximum values for x and y axes using the axis command in the following way − The axis command allows you to set the axis scales. When you run the file, MATLAB generates the following graph − Setting Axis Scales The following table shows the colors and their codes − Code MATLAB provides eight basic color options for drawing graphs. MATLAB generates the following graph − Setting Colors on Graph The following example demonstrates the concept − Example You can draw multiple graphs on the same plot. MATLAB generates the following graph − Drawing Multiple Functions on the Same Graph The axis square command generates a square plot. The axis equal command allows generating the plot with the same scale factors and the spaces on both axes. The grid on command allows you to put the grid lines on the graph. The title command allows you to put a title on the graph. The xlabel and ylabel commands generate labels along x-axis and y-axis. MATLAB allows you to add title, labels along the x-axis and y-axis, grid lines and also to adjust the axes to spruce up the graph. MATLAB draws a smoother graph − Adding Title, Labels, Grid Lines and Scaling on the Graph Please note that as we decrease the increment, the graph becomes smoother.Ĭhange the code file a little, reduce the increment to 5 − In this example, we will draw two graphs with the same function, but in second time, we will reduce the value of increment. Let us take one more example to plot the function y = x 2. ![]() When you run the file, MATLAB displays the following plot − ![]() Let us plot the simple function y = x for the range of values for x from 0 to 100, with an increment of 5.Ĭreate a script file and type the following code − To plot the graph of a function, you need to take the following steps −ĭefine x, by specifying the range of values for the variable x, for which the function is to be plottedįollowing example would demonstrate the concept. ![]()
