I have the polynomial: f(x) = x^7 - 4.75x^6 + 10.875x^5 - 20.125x^4 + 20x^3 + 1.75x^2 - 30x + 25
I need to use the convolution method to multiply all the linear factors of this polynomial together to find a new polynomial.

I don't know what that means, but you can see the coefficients and you can read the help about conv() function which does convolution. However, you have to have two functions to convolve, not one . There is a function called prod() that multiplies array elements together, eg
theProduct = prod([1, -4.75, 10.875, -20.125, 20, 1.75, 30, 25]);
