We can create both plane circles and solid circles in MATLAB.

So, in this article, we learnt how to create circles in MATLAB. Next, we define the angle theta as required. 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.
