functions in convol.i - c

    convol(a,b)  


returns convolution of vector a with vector b, a vector  
of length na+nb-1 where na=numberof(a), nb=numberof(b).  
In detail, for i=[1 to na+nb-1]  
  result(i) = sum j=[max(1,1+i-nb) to min(na,i)] (a(j)*b(1+i-j))  
The n0= and n1= keywords can be used to control the section of  
the full array that is actually returned, 1<=n0 line 6
