Write a MATLAB function, called arbpoly, that computes a
polynomial arbitrary nth degree. The function will take 2
inputs:
1) the first input will be a row vector, c, containing the
coefficients of the polynomial, starting with the coefficient of
the highest - degree term;
2) the second input will be a scalar, x, which is a real number
at which the polynomial will be evaluated.
The function's only output, y, will be the scalar value of the
polynomial computed...
