Here we discuss an introduction, how to Create a circle using rectangle function, a Solid 2D Circle, a circle in MATLAB and Simple arc. We can also format our circle as per our requirement. We also learnt how we can leverage the Rectangle function to plot circles in MATLAB. We can create solid or plane circles in MATLAB, which we will learn as we go ahead in the article.

We will learn how to create various types of circles in MATLAB. In this article, we will focus on circles. We can create both plane circles and solid circles in MATLAB. MATLAB can be used to perform operations involving geometric figures like circles, rectangles, squares etc. matlab find position of value in array I need to extract the data set peak width at this height but none of the array values are equal to this height value. So, in this article, we learnt how to create circles in MATLAB. The program dictates that if a equals 1 (one condition), b should be multiplied by 2 (an action), but if a does not equal 1 (another condition). On the first iteration, A is false, so the if block executes since A is true. for k 1:4 if A disp ( IF block ) A true else disp ( ELSE block ) end end.

Next, we define the angle theta as required. Wrap the if/else block in a for loop so that it executes four times. First we define the parameters of required arc.Ģ. As we know that arc is nothing but a small portion of the circle, code for creating an arc is also very similar to that of creating a circle.ġ. How we can Create a Simple arc in MATLAB?įinally, let us discuss how we can create a simple arc in MATLAB. We have passed ‘FaceColor’ as “b” so our output circle will be of Blue colour. Like we discussed in above examples, we will declare the radius and centre co-ordinates of the required circle. Let us now learn how to create a circle in MATLAB using rectangle function: Here is a simple code to achieve this:ġ. How to create a Circle in MATLAB Using Rectangle Function? + (colInImage - centerOfX).^2 <= radius.^2 = meshgrid(1 : imageSizeOfX, 1 : imageSizeOfY)

This is how our input and output will look like in MATLAB console: In the above line of code, Pixels is “logical” array and is 2D.

+ (colInImage – centerOfX).^2 <= radius.^2 ģ.

Pixels = (rowsInImage – centerOfY).^2 ….

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.
