Download e-book for kindle: GNU Octave Manual Version 3 by John W Eaton

By John W Eaton

This guide is the definitive advisor to GNU Octave, an interactive setting for numerical computation. GNU Octave offers a handy command-line interface for fixing linear and nonlinear difficulties utilizing vectors and matrices. This up-to-date version of the handbook covers model three of GNU Octave, and comprises documentation for brand spanking new positive factors corresponding to sparse matrices, linear programming and computational geometry. GNU Octave is unfastened software program, dispensed below the GNU basic Public License (GPL). all of the cash raised from the sale of this booklet helps the advance of loose software program. for every replica bought $1 might be donated to the GNU Octave improvement Fund. concerning the authors: John W. Eaton is the unique developer of GNU Octave.

Readline is very flexible and can be modified through a configuration file of commands (See the GNU Readline library for the exact command syntax). inputrc’. Octave provides two commands for initializing Readline and thereby changing the command line behavior. read_readline_init_file (file ) [Built-in Function] Read the readline library initialization file file.

Built-in Function] Chapter 4: Numeric Data Types uint32 (x ) 39 [Built-in Function] Convert x to unsigned 32-bit integer type. int64 (x ) [Built-in Function] Convert x to 64-bit integer type. uint64 (x ) [Built-in Function] Convert x to unsigned 64-bit integer type. intmax (type ) [Built-in Function] Return the largest integer that can be represented in an integer type. The variable type can be int8 signed 8-bit integer. int16 signed 16-bit integer. int32 signed 32-bit integer. int64 signed 64-bit integer.

The arguments to all of Octave’s bitwise operations can be scalar or arrays, except for bitcmp, whose k argument must a scalar. In the case where more than one argument is an array, then all arguments must have the same shape, and the bitwise operator is applied to each of the elements of the argument individually. If at least one argument is a scalar and one an array, then the scalar argument is duplicated. Therefore bitget (100, 8:-1:1) is the same as bitget (100 * ones (1, 8), 8:-1:1) It should be noted that all values passed to the bit manipulation functions of Octave are treated as integers.
