Jiro<\/a>'s pick this week is settingsdlg<\/tt><\/a> by Rody Oldenhuis<\/a>.\r\n <\/p>\r\n

Last December, I wrote this post<\/a> on inputsdlg<\/tt><\/a> by Kesh<\/a>. I really liked the flexibility of inputsdlg<\/tt> in creating a complex user input dialog. Today, I came across settingsdlg<\/tt> by Rody. There are a lot of similarities between the two functions. For example, they both allow prompting for multiple inputs,\r\n specifying input format, and storing output as a structure. While the customizability of settingsdlg<\/tt> is not as exhaustive as inputsdlg<\/tt>, I am impressed at the ease of use of the function.\r\n <\/p>

[settings, button] = settingsdlg(...<\/span>\r\n   'Description'<\/span>                        , ['This dialog will set the '<\/span>, ...<\/span>\r\n                                          'parameters used by FMINCON()'<\/span>], ...<\/span>\r\n   'title'<\/span>                              , 'FMINCON() options'<\/span>, ...<\/span>\r\n   'separator'<\/span>                          , 'Unconstrained\/General'<\/span>, ...<\/span>\r\n   {'This is a checkbox'<\/span>; 'Check'<\/span>}      , [false, false],...<\/span>\r\n   {'Tolerance X'<\/span>;'TolX'<\/span>}               , 1e-6, ...<\/span>\r\n   {'Tolerance on Function'<\/span>;'TolFun'<\/span>}   , 1e-6, ...<\/span>\r\n   'Algorithm'<\/span>                          , {'active-set'<\/span>,'interior-point'<\/span>}, ...<\/span>\r\n   'separator'<\/span>                          , 'Constrained'<\/span>, ...<\/span>\r\n   {'Tolerance on Constraints'<\/span>;'TolCon'<\/span>}, 1e-6)<\/pre>
settings = \r\n        Check: 0\r\n         TolX: 1.0000e-006\r\n       TolFun: 1.0000e-006\r\n    Algorithm: 'active-set'\r\n       TolCon: 1.0000e-006\r\nbutton =\r\nok\r\n<\/pre>
 <\/p>\r\n   
As you can see, it takes parameter-value pairs. The type of input is automatically determined by the value: numbers and strings\r\n      use edit boxes, cell arrays use list boxes, and logical arrays use check boxes. You can also group fields by creating separators.\r\n   <\/p>\r\n   
I also like the detailed documentation (.pdf) that Rody includes with the entry. And finally, if you're looking for an example\r\n      of a well-written MATLAB code, take a look at this entry. It's very well-commented and has a lot of error checking to make\r\n      it robust.\r\n   <\/p>\r\n
