Select a Default date and time format option to specify the default format of theDatetime object. You also can enter a custom format. For more information, see the Format property for datetime arrays.
Select a Default date-only format option to specify the default date format of theDatetime object. You also can enter a custom format. For more information, see the Format property for datetime arrays.
Display	Select Wrap lines to make each line of input or output in the Command Window break into multiple lines to fit within the current width of the Command Window.For details, see Wrap Lines of Code to Fit Window Width.
Select Set matrix display width to eighty columns to limit the width of matrix output.If you also select Wrap lines, and the width of the Command Window is fewer than 80 characters, each row of 80 characters of matrix output wraps to fit within the width of the Command Window.
Select Show getting started message bar to display the Command Window message bar that provides links to introductory information.
Select Suggest corrections for mistyped functions and variables to display suggestions in the Command Window. If you enter an undefined function, variable name, or MATLAB® operator, MATLAB displays:Did you mean:followed by a suggested command at the command line. You can pressEnter to run that command orEsc to delete the suggestion.
Number of lines in command window scroll buffer specifies the maximum number of lines displayed in the Command Window. A larger scroll buffer provides a larger base for search features, but requires more memory. By default, the scroll buffer is set to 5,000 lines.The scroll buffer size does not impact the number of lines that you can recall. By default, you can use the up arrow key ↑ to recall all lines shown in the Command History, regardless of how many lines you see in the Command Window.
