Create the following functions using MATLAB

Write a function called sindeg that takes a matrix input called deg. The function returns a matrix of the same size as deg with each of its elements containing the sine of the corresponding element of deg. Note that the elements of deg are given in degrees and not radians. As a second output, the function returns a scalar that contains the average value of the first output. You are not allowed to use the sind and cosd built-in functions, but the use of any other function is acceptable. Write a function called halfsum that takes as input an at most two- dimensional array A and computes the sum of the elements of A that are in the lower right triangular part of A, that is, elements in the counter-diagonal (going from the bottom left corner, up and to the right) and elements that are to the right of it. For example, if the input is [1 2; 3 4; 5 6; 7 8], then the function would return 21
