The original R-MATLAB cheat sheet was taken from ©2006 Vidar Bronken Gundersen, /mathesaurus.sf.KillVariables or KillStrings or KillWaves Perspective plots of surfaces over the x-y plane Description Make/N=(2,2,2) a=ģd data Contour and image plots DescriptionĭisplayHelpTopic "ModifyGraph for Traces" Searching available documentation Descriptionĭuplicate a,b b = a > 5.5 ? p : NaN Right-click function name "Help for function" or ⎇+ ⌘+ F1 Perspective plots of surfaces over the x-y plane | Matrix- and elementwise- multiplication | IGOR Pro is a scientific data analysis software, numerical computing environment and programming language that runs on Windows or Mac operating systems.

Testing Run internal unit tests with:: nosetests -with-doctest -doctest-tests igor test The data in the test/data. Just change:: import igor to:: import igor.igorpy as igor in your calling code. If a sequence was created with just these. The part to the right of the equal sign can be any valid expression. This work is mainly by Vidar Bronken Gundersen and Ben Gallarda, see Credits for details. For example:: igorbinarywave.py -help For users transitioning from igor.py, theres a compatibility module exposing the old interface. This can typically be a channel or a variable. Each value in the wave is replaced by its sine. Type the command w sin (w) In the command line and press Enter. Suppose you have a wave named w and you would like to replace its values with the sine of its values. Equivalents are given for commands, gathered under a set of headings. Igor makes it very simple to compute with waves. We’re going to start with (more or less) the version of this method that has already benefited from the previous two refactoring blog posts.This is a short guide to translate commands in three different numerical analysis software packages: R, MATLAB and IGOR Pro. If not present ODBC administrator can be downloaded directly from the Apple. Now seems like a good time to turn our attention to them. Then move the alias to Igor Pro/Igor Extensions or a similar folder that. You may have noticed we’ve been ignoring the series of ifs that make up the main body of the method. In the last two articles, we’ve been looking at the smells from a single method, validateQuery. Remember that by ‘smell’ I mean ‘code that you should look carefully at to see if there’s a simpler/easier-to-understand approach.’ I don’t mean ‘if statements are evil never use them.’ If statements are very useful, and often the right tool for the job, but they can also be a smell. We could use a hammer for every job around the house, but we don’t (well…). We could program in assembler but we don’t. But even though these basic building blocks exist, it doesn’t mean they should be our goto strategy (see what I did there?) every time. They’re a fundamental part of languages like Java. I’m not intending to go after any sacred cows or anything – for loops and if statements are pretty much the first things we learn in many programming languages. Today, I’m talking about if statements (conditionals). Each unit can contain statements that specify a transfer of control (for example, GO TO). The article in this series that has so far provoked the most responses was on iteration. If a nonexecutable statement is used, the result can be unpredictable.
