Hi gang!

        Given the sophistication of some of the sinc.m's i received 
today, the tidbit i am about to offer up may wind up being the octave 
equivalent of boiled water .... so bare with me and send me mail if you 
all did this already :-)

        I just finished up writing an m file for convolution. As I have 
not looked at how anybody else has done it ( meaning, I did not copy the 
matlab one! ). I would be happy to make it available.

        The algorithm is frankly, wretched, ( i have not puzzled out the 
growth rate yet other then to look at the algorithm  and say to my self:
 " yup, that is pretty bad! ") but it has the advantage of operating in 
the manner that most people seem to use to think about convolution when 
forced to work it out by hand.

        So let me know if I have just reinvented the wheel!

        idiocy is the impulse function in the convolution of life
