$3.$ Create a MATLAB function named vectorAnalysis that takes a vector as input and performs the following tasks:

a$.$ Calculate the mean, median, standard deviation, and range of the vector.

b$.$ Identify and return the indices of the maximum and minimum values in the vector.

c$.$ Determine and return the first and last occurrence of the most frequently appearing element in the vector.

Test the function with two different vectors: v$1=[15,22,15,8,-3,15,7,22]$ and v$2=[3\mathrm{.}5,-1\mathrm{.}8,3\mathrm{.}5,7\mathrm{.}2,-4\mathrm{.}6,2\mathrm{.}9,3\mathrm{.}5,-1\mathrm{.}8].$ Include in your submission the function definition, the test code, and the results for both vectors.
