Description

You can use the format function to return information about the current display format in the Command Window. That information is stored in a DisplayFormatOptions object. The object has two properties: NumericFormat stores the numeric display format, and LineSpacing stores the line spacing display format. You can also call format with a DisplayFormatOptions object as the input argument to restore the display settings saved in that object.

Creation

Create a DisplayFormatOptions object by calling the format function with an output argument.

Save the current display format and restore it at a later time.

Set the numeric display to shortE and display a 2-by-2 matrix of numeric values.

format shortE
m = [9638573934 37467; 236 574638295]
m = 2×2

   9.6386e+09   3.7467e+04
   2.3600e+02   5.7464e+08

Save the current display format in oldFmt and change the numeric format to longE.

oldFmt = format("longE")
oldFmt = 
  DisplayFormatOptions with properties:

    NumericFormat: "shortE"
      LineSpacing: "loose"

Confirm that the numeric format is now long, scientific notation by redisplaying matrix m.

m
m = 2×2

     9.638573934000000e+09     3.746700000000000e+04
     2.360000000000000e+02     5.746382950000000e+08

Restore the format to its previous state. Redisplay m to confirm that the numeric format is now short, scientific format.
