GNU Octave is software featuring a high levelprogramming language, primarily intended for numerical computations. 2200 Machine Type And Serial Number Are Invalid Lenovo. Octave helps in solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch oriented language. Since it is part of the GNU Project, it is free software under the terms of the GNU General Public License. Octave is one of the major free alternatives to Matlab, others being Scilab and Free. Mat. 4567 Scilab, however, puts less emphasis on bidirectional syntactic compatibility with Matlab than Octave does. HistoryeditThe project was conceived around 1. Banjodoline is a Virtual Banjo and Mandolin VST plugin, including a Banjolin, Octave Mandolin and Electric Mandolin instruments. Banjo VST, Mandolin VST software. At first it was intended to be a companion to a chemical reactor design course. Real development was started by John W. Eaton in 1. 99. 2. The first alpha release dates back to January 4, 1. February 1. 7, 1. Version 4. 0. 0 was released on May 2. The program is named after Octave Levenspiel, a former professor of the principal author. Levenspiel is known for his ability to perform quick back of the envelope calculations. DevelopmentseditIn addition to use on desktops for personal scientific computing, Octave is used in academia and industry. For example, Octave was used on a massive parallel computer at Pittsburgh supercomputing center to find vulnerabilities related to guessing social security numbers.

Technical detailseditOctave, the languageeditThe Octave language is an interpreted programming language. It is a structured programming language similar to C and supports many common C standard library functions, and also certain UNIX system calls and functions. However, it does not support passing arguments by reference. Octave programs consist of a list of function calls or a script. The syntax is matrix based and provides various functions for matrix operations. It supports various data structures and allows object oriented programming. Its syntax is very similar to Matlab, and careful programming of a script will allow it to run on both Octave and Matlab. Because Octave is made available under the GNU General Public License, it may be freely changed, copied and used. The program runs on Microsoft Windows and most Unix and Unix likeoperating systems, including mac. OS. 1. 7Notable featureseditCommand and variable name completioneditTyping a TAB character on the command line causes Octave to attempt to complete variable, function, and file names similar to Bashs tab completion. Octave uses the text before the cursor as the initial portion of the name to complete. Command historyeditWhen running interactively, Octave saves the commands typed in an internal buffer so that they can be recalled and edited. Data structureseditOctave includes a limited amount of support for organizing data in structures. In this example, we see a structure x with elements a, b, and c, an integer, an array, and a string, respectively octave 1 x. Short circuit boolean operatorseditOctaves and logical operators are evaluated in a short circuit fashion like the corresponding operators in the C language, in contrast to the element by element operators and. Increment and decrement operatorseditOctave includes the C like increment and decrement operators and in both their prefix and postfix forms. Octave also does augmented assignment, e. Unwind protecteditOctave supports a limited form of exception handling modelled after the unwindprotect of Lisp. The general form of an unwindprotect block looks like this unwindprotectbodyunwindprotectcleanupcleanupendunwindprotect. As a general rule, GNU Octave recognizes as termination of a given block either the keyword end which is compatible with the Matlab language or a more specific keyword endblock. As a consequence, an unwindprotect block can be terminated either with the keyword endunwindprotect as in the example, or with the more portable keyword end. The cleanup part of the block is always executed. In case an exception is raised by the body part, cleanup is executed immediately before propagating the exception outside the block unwindprotect. GNU Octave also supports another form of exception handling compatible with the Matlab language trybodycatchexceptionhandlingend. This latter form differs from an unwindprotect block in two ways. First, exceptionhandling is only executed when an exception is raised by body. Second, after the execution of exceptionhandling the exception is not propagated outside the block unless a rethrow lasterror statement is explicitly inserted within the exceptionhandling code. Variable length argument listseditOctave has a mechanism for handling functions that take an unspecified number of arguments without explicit upper limit. To specify a list of zero or more arguments, use the special argument varargin as the last or only argument in the list. Variable length return listseditA function can be set up to return any number of values by using the special return value varargout. For example functionvarargout multiassign datafork1 nargoutvarargoutkdata ,k endend. C integrationeditIt is also possible to execute Octave code directly in a C program. For example, here is a code snippet for calling rand1. Column. Vector. Num. Rands2 Num. Rands01. Num. Rands11 octavevaluelistfarg,fret farg0octavevalueNum. Rands fretfevalrand,farg,1 Matrixunisfret0. C and C code can be integrated into GNU Octave by creating oct files, or using the Matlab compatible MEX files. Matlab compatibilityeditOctave has been built with Matlab compatibility in mind, and shares many features with Matlab Matrices as fundamental data type. Built in support for complex numbers. Powerful built in math functions and extensive function libraries. Extensibility in the form of user defined functions. Octave supposedly treats incompatibility with Matlab as a bug therefore, it could be considered a software clone, which does not infringe software copyright as per Lotus v. Borland court case. Matlab scripts from the Math. Works File. Exchange repository are compatible with Octave, but cant be used legally due to the Terms of use. While often provided and uploaded by users under an Octave compatible and proper Open source. BSD license, the fileexchanges Terms of use prohibit any usage beside Math. Works proprietary Matlab. Syntax compatibilityeditThere are a few purposeful, albeit minor, syntax additions Comment lines can be prefixed with the character as well as the  character Various C based operators, ,, , are supported Elements can be referenced without creating a new variable by cascaded indexing, e. Strings can be defined with the character as well as the character When the variable type is single, Octave calculates the mean in the single domain Matlab in double domain which is faster but gives less accurate results Blocks can also be terminated with more specific Control structure keywords, i. Functions can be defined within scripts and at the Octave prompt All operators perform automatic broadcasting or singleton expansion. Presence of a do until loop similar to do while in C.
