deconv
Deconvolution
(Q,R)=deconv(a, b)
Inputs
a A vector of real numbers.
b A vector of real numbers.
Outputs
Q A vector of real numbers.
R A vector of real numbers.


Description
deconv(a,b) returns the vectors Q and R such that
    conv(Q,b) + R = a
Example
>>a=[2 3 4 5]'
>>b=[7 8 9]'
>>(Q,R)=deconv(a,b)
>>conv(Q,b)+R-a
