The text of a DEMO program for identification of the kernel of multidimensional Urysohn operator.

Multidimentional integral operator of Urysohn type

Technical task is to identify kernel U[x,y,s], which is three dimensional function, provided recorded inputs x(t), y(t) and output z(t)

Algorithm is shown in DEMO program, mathematical details can be found in the article
