create a function in matlab that does the following with the given material:

- implement a function that computes a kernel based on the Gaussian filter

- the function receives the mean, variance and kernel size

- returns the kernel

- use the image provided to demonstrate with at least 5 different kernels provided

(please include an explanation of what each part of the code does)

\begin{tabular}{|l|l|l|} \hline media & varianza & kernel size \\ \hline 0.0 & 1000.0 & 33 \\ \hline 0.0 & 2.0 & 33 \\ \hline-3.0 & 1.0 & 33 \\ \hline 0.0 & 4.0 & 55 \\ \hline-6.0 & 0.5 & 77 \\ \hline \end{tabular}
