To see which type is currently in use, type To maintain a format across sessions, use MATLAB preferences. The specified format applies only to the current MATLAB session. Setting format to short or long does not affect the display of integer variables. For example, MATLAB uses three digits to display numbers of type int8 (i.e., -128:127).
MATLAB always displays integer variables to the appropriate number of digits for the class. Computations on integer variables are done natively in integer. Contrast with compact.Ĭomputations on floating-point variables, namely single or double, are done in appropriate floating-point precision, no matter how those variables are displayed. Contrast with loose.Īdds linefeeds to make output more readable. Suppresses excess line feeds to show more output in a single screen. Use these format types to used to affect the spacing in the display of all variables. Hexadecimal (hexadecimal representation of a binary double-precision number)
Use these format types to switch between different output display formats for all numeric variables. Scaled fixed point format, with 15 digits for double 7 digits for single.įloating point format, with 15 digits for double 7 digits for single.īest of fixed or floating point, with 5 digits.īest of fixed or floating point, with 15 digits for double 7 digits for single.Įngineering format that has at least 5 digits and a power that is a multiple of threeĮngineering format that has exactly 16 significant digits and a power that is a multiple of three Use these format types to switch between different output display formats for floating-point variables. The tables below show the allowable values for type, and provides an example for each type using pi. The tables shown below list the allowable values for type. For floating-point variables, for example, the default is format short (i.e., 5-digit scaled, fixed-point values).Ĭhanges the format to the specified type. The format function affects only how numbers are displayed, not how MATLAB computes or saves them.īy itself, changes the output format to the default appropriate for the class of the variable currently being used. Use the format function to control the output format of numeric values displayed in the Command Window. Select Preferences from the File menu in the MATLAB desktop and use Command Window preferences.
