Write a user-defined function that multiplies two polynomials. Name the function p=polymul t (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
Check the answer with MATLAB's built-in function conv.
