The default userpath uses the benefits provided by the When you upgrade to a newer version of MATLAB, the software automatically continues to use the same startup The first time you run a new version of MATLAB, the software automatically creates the You can always run your files because MATLAB automatically adds the userpath folder to You can store the MATLAB files you work with in one folder, such as For more information, see Select MATLAB Icon. Choose an option for the Initial workingĪlternatively on Windows platforms, specify the initial working folder in the MATLAB shortcut icon. Preferences options in the Preferences Window. Starting in R2014b, you can change the startup folder using the General On Linux ® platforms, the default startup folder is the folder from which youįor more information, see Start MATLAB on Linux Platforms.

If you start MATLAB by double-clicking the MATLAB shortcut icon and the startup folder is set to an unexpected For example, the following statement adds the user-defined folder /home/myname/mytools to the search path.

Use startup.m to modify the default search path, predefine variables in your workspace, or define defaults for graphics objects. If the Use new figure option is set to false, then MATLAB uses the properties from an open Figure window to determine the appearance of code-generated figures. Last working folder from the previous MATLAB session or the custom path specified in theĬommand (To use the folder specified by the If the Use new figure option in the Publish settings pane is set to true, then in the published output, MATLAB uses a Figure window at the default size and with a white background. Double-click the MATLAB icon on your Windows ® desktop or in the Start menu % Some function that requires 2 inputs and has some optional inputs.Įrror('myfuns:somefun2Alt:TooManyInputs'. Here's a way to set the defaults in one location and then overwrite the ones the user specified. If I decide to change a default setting for one value, I have to update each relevant case. Opt3 = code is verbose and, in my opinion, not very pretty. In Open with window, give the path as Matlabbinwin32MATLAB.exe and. % Some function with 2 required inputs, 3 optional.Įrror('myfuns:somefun2:TooManyInputs'. In Control Panel, click on Default Programs- Set Associations, select. type somefun2įunction y = somefun2(a,b,opt1,opt2,opt3) To set default values in somefun2, I could use a switch statement or use if-elseif constructs. Here's another way I could write this function header, using varargin. dbtype somefun2 1ġ function y = somefun2(a,b,opt1,opt2,opt3) In this scenario, once they choose to set an optional input, they must set all the optional ones that precede it in the argument list. Suppose my function requires the first 2 inputs, but there are 3 others that the user can choose to set, or allow them to take default values. Note that neither of these methods checks the validity of the overridden elements. If the arguments are specified by their order, and not by parameter-value pairs, there is a nice way to accomplish this take advantage of varargin. Sometimes I want to write a function that has some required inputs and some optional trailing arguments.
