Write a function mathematica

And finally, simple code tends to be much easier to read and understand. Good code, though, is broken up into functions and definitions that are each as simple and self-contained as possible. Even in very large Wolfram Language programs, there may be no individual definitions longer than a handful of lines. A sign of a good function name is that when you read it in a piece of code, you immediately know what the code does.

My recommendation is to Never do anything liek this I see no point in using something like this on real production environments. Whether or not you think this is a good idea probably depends on your appetite for procedural code in your DBMS and your liking for learning complex new languages.

While the SQL-building proc would work, I think John's right in suggesting that you don't use his otherwise-correct answer! You don't say what form your repeated lines take, so I'll offer three potential alternatives, starting with the simplest: Accept that procedural SQL is a primitive language lacking so many "essential" constructs that you wouldn't use it at all if it wasn't the only option.

Move your procedural operations outside of the DBMS and execute them in code written in a more sophisticated language. Consider ways in which your architecture could be adjusted to extract business logic from your data storage platform hey, why not redesign the whole thing!

Write code to generate, as part of your build process, the stored procedures. That way if the repeated lines ever need to change, you can change them in one place and automatically generate the repetition.

I thought of another one as I was typing; consider it a bonus.10 Tips for Writing Fast Mathematica Code. December 7, The Compile function takes Mathematica code and allows you to pre-declare the types (real, complex, etc.) and structures (value, list, and having clean, organized code should make it easier to write good code.

But the key feature in this context is the profiler that lets you see. printf format string refers to a control parameter used by a class of functions in the input/output libraries of C and many other programming urbanagricultureinitiative.com string is written in a simple template language: characters are usually copied literally into the function's output, but format specifiers, which start with a % character, indicate the location and method to translate a piece of data (such.

The formal parameters are # (or #1), #2, etc. Function[x, body] is a pure function with a single formal parameter x. Function[{x1, x2, }, body] is a pure function with a list of formal parameters.

Function[params, body, attrs] is a pure function that is treated as . Jun 20,  · You would write it, for ex. 40! See the Wolfram Mathematica Help for other recursive functions. I want to build a recursive function, and the foctorial is just an example, not that I want the factorial itself, but I want to know how to write a recursive function through a simple example, like the.

I defined some variable in the beginning of a Mathematica notebook and used it afterwards to calculate my results. Now I want to do the same calculation several times for different values of the variable and use the results somewhere.

With over a million users around the world, the Mathematica software system created by Stephen Wolfram has defined the direction of technical computing for the past decade.
