Consider a program involving at least one numerical analysis technique (other than interpolation or curve fitting) that we have discussed in this course and that could be used in your (intended) field or that could be of use to you as a student. This program should be distinct from any other program you have discussed in a discussion previously. First, in plain English, describe the program and how it works. If the program is especially complex, you may instead examine a smaller discernible section of the program for this discussion. Based on your plain English description of the program, share one or more code fragments that you write for this discussion post to illustrate the concept of your selected numerical analysis technique in your program. If the program is especially complex, you may instead share a smaller discernible section of the program for this discussion, but be sure that the subset of the program includes at least one use of a numerical analysis technique (other than interpolation or curve fitting).
