By Hans Petter Langtangen
The ebook serves as a primary advent to desktop programming of clinical functions, utilizing the high-level Python language. The exposition is instance and problem-oriented, the place the purposes are taken from arithmetic, numerical calculus, data, physics, biology and finance. The publication teaches "Matlab-style" and procedural programming in addition to object-oriented programming. highschool arithmetic is a required historical past and it truly is effective to check classical and numerical one-variable calculus in parallel with studying this ebook. along with studying find out how to application pcs, the reader also will the best way to clear up mathematical difficulties, coming up in quite a few branches of technological know-how and engineering, due to numerical equipment and programming. by means of mixing programming, arithmetic and medical purposes, the booklet lays a great origin for training computational science.
From the reviews: Langtangen … does an outstanding task of introducing programming as a suite of abilities in challenge fixing. He publications the reader into pondering correctly approximately generating application good judgment and information constructions for modeling real-world difficulties utilizing gadgets and features and embracing the object-oriented paradigm. … Summing Up: hugely recommended.

Those folks who've discovered medical programming in Python ‘on the streets’ can be a little jealous of scholars who've the chance to take a direction out of Langtangen’s Primer.”
John D. cook dinner, The Mathematical organization of the United States, September 2011
This ebook is going via Python particularly, and programming mostly, through initiatives that scientists will most likely practice. It comprises worthy information for scholars new to medical computing and often is the excellent bridge among an advent to programming and a sophisticated path on numerical tools or computational science.
Alex Small, IEEE, CiSE Vol. 14 (2), March /April 2012
“This fourth version is an excellent, inclusive textbook that covers pretty well every little thing one must be aware of to head from 0 to particularly subtle medical programming in Python…”

Fig. 2 An Idle editor window containing our first one-line program. Your program is now in the Idle editor, but before you can run it, the program text must be saved in a file. Choose File and then Save As. As usual, such a command launches a new window where you can fill in the name of the file where the program is to be stored. And as always, you must first check that you are in the right folder, or directory which is Idle’s word for the same thing. The upper line in the file dialog window contains the folder name.

The first two declared variables have this form. 9 10 1 Computing with Formulas With such long variables names, the code for evaluating the formula becomes so long that we have decided to break it into two lines. ). We note that even if this latter version of the program contains variables that are defined precisely by their names, the program is harder to read than the one with variables v0, g, t, and y0.
