Please check the help files of the matlab circular convolution . Matlab already has a readymade function for it.
You would have to write your own code for a modulation (Matlab has a convolution function not in the tools), otherwise you can use its built in function in the signal processing toolbox.

To decompose an image in MATLAB, you can use the im2col function to reshape the image into overlapping or non-overlapping blocks, or apply techniques like Discrete Wavelet Transform (DWT) using the wavedec2 function for multi-resolution analysis. For example, to perform a wavelet decomposition, you can use: [coeffs, sizes] = wavedec2(image, level, 'waveletname'); Replace level with the desired decomposition level and 'waveletname' with the chosen wavelet type. You can then extract the approximation and detail coefficients from coeffs as needed.

matlab code for convolutional coding and BCH coding
Please check the help files of the matlab circular convolution . Matlab already has a readymade function for it.
To write code in MATLAB, you can use the MATLAB Editor, which allows you to create scripts and functions. You begin by opening a new script file, where you can input your code, including variables, loops, and functions. Once your code is written, you can save the file with a .m extension and run it by typing the filename in the command window. MATLAB also provides extensive documentation and built-in help to assist with coding.

Initially, the equation can be directly realized using Matlab source code. Then various inputs can be applied to it. These values can easily be plotted on a graph using plot or stem command in Matlab.
