If the second argument is an integer n, the arguments areīuilt-in Function: argnames ( fun) Return a cell array of character strings containing the names of They are the names of the arguments of the function. Then, start the GNU Octave by clicking the icon in the programs menu or launch the interactive prompt by typing octave in a terminal. g., myfun), a function handle (e.g., myfun) or a cell array.

If the second and subsequent arguments are character strings, First, follow the installation instructions for: or consult the GNU Octave manual to install GNU Octave on your system. Next: Test Plotting Functions, Previous: Printing and Saving Plots, Up: High-Level. GNU Octave Manual Version 3: See the print edition: Network Theory Limited. I am new to GNU Octave and I want to plot the function psi in the range of 0 : 2000: function y H(x) if (x > 0) y 1 else y 0 endif endfunction function y psi(s) t 200 phiabs 500 K 1000 n0 1000 y -n0 e. Return a cell array of character strings containing the names of the arguments of the inline function fun.
#Gnu octave array of functions code#
The following code defines the function f(x) x2 + 2. All arguments followed by a parenthesis are considered An inline function is created from a string containing the function body using the inline function. It shouldīe noted that i, and j are ignored as arguments due to theĪmbiguity between their use as a variable or their use as an inbuiltĬonstant. The generatedįunction arguments will then be in alphabetical order. If called with a single argument, the arguments of the generatedįunction are extracted from the function itself. ) Built-in Function: inline ( str, n) Create an inline function from the character string str. The following code defines theĪfter this it is possible to evaluate f at any x byīuilt-in Function: inline ( str) Built-in Function: inline ( str, arg1. The same idea can be implemented more easily through the use of the cellfun function that calls a user-specified function on all elements of a cell array. The simplest way to process that data is to iterate through it using one or more for loops. An inline function is created from a string containing the functionīody using the inline function. Data that is stored in a cell array can be processed in several ways depending on the actual data.
