Details

The algorithm used in the methods presented in this Demonstration is based on the Newton backward difference interpolating polynomial. The problem is integrated over the interval , and is replaced by a polynomial obtained using Newton's backward difference interpolation scheme. The regions of absolute stability of the methods are found using the locus boundary method.

The control labels are described as follows:

"step number"—the step number of the method.

"initial range"—the value of in the interval .

"implicitness"—the value 0 is assigned to an explicit method, while the value 1 is assigned to an implicit method.
