Converts an expression from one unit to
another. The units must be in the same
category.
The _ underscore character designates the
units. For a list of valid pre-defined units,
refer to the chapter about constants and
measurement units in this book. You can
press:
TI-89: 2 9
TI-92 Plus: ¥ À to select units from a
menu, or you can type the unit names
directly.
To get the _ underscore when typing units
directly, press:

10^( squareMatrix1 ) ⇒ squareMatrix
Returns 10 raised to the power of
squareMatrix1 . This is not the same as
calculating 10 raised to the power of each
element. For information about the
calculation method, refer to
cos() .
squareMatrix1 must be diagonalizable. The
