edge, a FORTRAN90 code which defines some test functions in 1D, 2D and 3D for the detection of edges, and uses gnuplot() to display images of the functions.

In particular, we look at some simple functional examples in 1D, 2D, and 3D, that is, situations in which a formula is supplied so that the value of a scalar quantity f() can be determined at any point in the region. We are interested in examples in which the quantity f() exhibits jumps. that is, sudden, sharp changes in value.
