log()
/s keys
log(Expr1[,Expr2]) ⇒ expression
log(List1[,Expr2]) ⇒ list
Returns the base-Expr2 logarithm of the
first argument.
Note: See also Log template, page 6.
For a list, returns the base-Expr2 logarithm
of the elements.
If the second argument is omitted, 10 is
used as the base.
If complex formatmode is Real:
If complex formatmode is Rectangular:
log(squareMatrix1[,Expr]) ⇒
squareMatrix
Returns the matrix base-Expr logarithm of
squareMatrix1. This is not the same as
calculating the base-Expr logarithm of
each element. For information about the
calculation method, refer to cos().
squareMatrix1 must be diagonalizable. The
result always contains floating-point
numbers.
If the base argument is omitted, 10 is used
as base.
In Radian angle mode and Rectangular
complex format:
