Helper to set default values (if not already set) of parameter struct. Takes input parameters and a list of 'name'/default pairs, and for each 'name' for which prm has no value (prm.(name) is not a field or 'name' does not appear in prm list), getPrmDflt assigns the given default value. If default value for variable 'name' is 'REQ', and value for 'name' is not given, an error is thrown. See below for usage details. USAGE (nargout==1) prm = getPrmDflt( prm, dfs, [checkExtra] ) USAGE (nargout>1) [ param1 ... paramN ] = getPrmDflt( prm, dfs, [checkExtra] ) INPUTS prm - param struct or cell of form {'name1' v1 'name2' v2 ...} dfs - cell of form {'name1' def1 'name2' def2 ...} checkExtra - [0] if 1 throw error if prm contains params not in dfs OUTPUTS (nargout==1) prm - parameter struct with fields 'name1' through 'nameN' assigned OUTPUTS (nargout>1) param1 - value assigned to parameter with 'name1' ... paramN - value assigned to parameter with 'nameN' EXAMPLE dfs = { 'x','REQ', 'y',0, 'z',[], 'eps',1e-3 }; prm = getPrmDflt( struct('x',1,'y',1), dfs ) [ x y z eps ] = getPrmDflt( {'x',2,'y',1}, dfs ) See also INPUTPARSER Piotr's Image&Video Toolbox Version 2.20 Copyright 2009 Piotr Dollar.
