MATLAB, also called Matrix Laboratory, is a computing environment and platform for programming languages. It was designed and developed by MathWorks. MATLAB — it is a framework that allows us to perform matrix manipulations, implement algorithms, display functions and data, create user interfaces and interact with programs written in different programming languages such as C, C ++, Python, Java, etc.
How to draw a color image in MATLAB?
A color image can be represented as a 3order matrix. The first order is for rows, the second order is for columns, and the third order is for specifying the color of the corresponding pixel. We are using RGB color format here, so the third order will take 3 values Red, Green and Blue, respectively. The row and column values depend on the size of the image.
Approach to draw the flag of Japan:
I (:,:,:) = 255;
((xh) ^ 2  (yk) ^ 2) = r ^ 2
where (h, k) & # 8212 ; centers, (x, y) — the xaxis and yaxis coordinates and the radius of the circle.
