function bool = isEnvironment(wantedEnvironment, varargin)
|
|
% ISENVIRONMENT check for a particular environment (MATLAB/Octave)
|
|
%
|
|
% This function returns TRUE when it is run within the "wantedEnvironment"
|
|
% (e.g. MATLAB or Octave). This environment can be tested to be a particular
|
|
% version or be older/newer than a specified version.
|
|
%
|
|
% Usage:
|
|
%
|
|
% ISENVIRONMENT(ENV)
|
|
% ISENVIRONMENT(ENV, VERSION)
|
|
% ISENVIRONMENT(ENV, OP, VERSION)
|
|
%
|
|
% Parameters:
|
|
% - `ENV`: the expected environment (e.g. 'MATLAB' or 'Octave')
|
|
% - `VERSION`: a version number or string to compare against
|
|
% e.g. "3.4" or equivalently [3,4]
|
|
% - `OP`: comparison operator (e.g. '==', '<=', '<', ...) to define a range
|
|
% of version numbers that return a TRUE value
|
|
%
|
|
% When `OP` is not specified, "==" is used.
|
|
% When no `VERSION` is specified, all versions pass the check.
|
|
%
|
|
% See also: isMATLAB, isOctave, versionCompare
