Example - 3-D Stem Plot of an FFTFor example, fast Fourier transforms are calculated at points around the unit circle on the Complex plane. So, it is interesting to visualize the plot around the unit circle. Calculating the unit circle.

In recent years, a large amount of software development activity has migrated from
the client to the server. The client-centric model, in which a client executes Complex
programs to visualize and manipulate data, is no longer considered appropriate for the
majority of enterprise applications. The principal reason is deployment—it is a
significant hassle to deploy client programs onto a large number of desktops, and to
redeploy them whenever the application changes. Instead, applications are redesigned
to use a web browser as a "terminal". The application itself resides on the server,
formatting data for the user as web pages and processing the responses that the user fills into web forms.
Advanced_modelling_in_finance_using_Excel_and_VBA（pdf） The book adopts a step-by-step approach to understanding the more sophisticated aspects of Excel macros and VBA programming, showing how these programming techniques can be used to model and manipulate financial data, as applied to equities, bonds and options. The book is essential for financial practitioners who need to develop their financial modelling skill sets as there is an increase in the need to analyse and develop ever more Complex what if scenarios.
PTypes (C++ Portable Types Library) is a simple alternative to the STL that includes multithreading and networking. It defines dynamic strings, variants, character sets, lists and other basic data types along with threads, synchronization objects, IP sockets and named pipes. PTypes also offers message queues as an alternative method of thread synchronization. Its main `target audience is developers of Complex network daemons, robots or non-visual client/server applications of any kind
Just what is a regular expression, anyway?
Take the tutorial to get the long answer. The short answer is that a regular expression
is a compact way of describing Complex patterns in texts. You can use them to search
for patterns and, once found, to modify the patterns in Complex ways. You can also use
them to launch programmatic actions that depend on patterns.
A tongue-in-cheek comment by programmers is worth thinking about: "Sometimes you
have a programming problem and it seems like the best solution is to use regular
expressions now you have two problems." Regular expressions are amazingly
powerful and deeply expressive. That is the very reason writing them is just as
error-prone as writing any other Complex programming code. It is always better to
solve a genuinely simple problem in a simple way when you go beyond simple, think
about regular expressions.
