conv
Convolution of vectors.
y=conv(a,b)
Inputs
a Any real vector
b Any real vector
Outputs
y Convolution of the inputs as defined below.


Description
conv(a, b) returns a vector c which is the convolution of the input vectors. Thus
    c[i] = a[i+1-k]*b[k] , k = 1,2,3,..... i , sum over k for each i
If a and b are vectors representing the coefficients of polynmials , conv(a,b) returns the coefficients of the product of the polynomials.
Example
>>// (2x^2+3x+2)(5x+8)=10x^3+31x^2+34x+16
>>conv([2 3 2],[5 8])
         10
         31
         34
         16
