MATLAB Write a user-defmed function that multiplies two polynomials. Name the function p=polymult (pl1 p2 ). The two input arguments pl and p2 are vectors of the coefficients of the two polynomials. The output argument p is the resulting polynomial. Use the function to multiply the following polynomials: f1(x) = 2x⁶- 3x⁴- 9x³
+ llx²- 8x + 4 and f2(x) = 5x³
+ 7x -10 **Write a comment (using % sign) in front or below each line of code explaining what that Matlab command is doing
