Hi,

This may be off topic but hopefully you won't mind too much:  I
recently "discovered" that many convolution operations can be
performed using partial differential equations, quite often some form
of the heat equation.  Is there some advantage to this, and when
would this be an appropriate route to take?

Thanks.
