Returns true
if all output fields are quoted. See CSV::new
for details.
Returns the list of break points where execution will be stopped.
See DEBUGGER__
for more usage
Returns a new binding each time near TOPLEVEL_BINDING for runs that do not specify a binding.
Set
an error (a protected method).
Return the appropriate error message in POSIX-defined format. If no error has occurred, returns nil.
Creates a new ipaddr containing the given network byte ordered string form of an IP address.
Creates a Range
object for the network address.
Set
date-time format.
datetime_format
A string suitable for passing to strftime
.
Returns the date format being used. See datetime_format=
Private. Use Matrix#determinant
Returns the determinant of the matrix, using Bareiss’ multistep integer-preserving gaussian elimination. It has the same computational cost order O(n^3) as standard Gaussian elimination. Intermediate results are fraction free and of lower complexity. A matrix of Integers will have thus intermediate results that are also Integers, with smaller bignums (if any), while a matrix of Float
will usually have intermediate results with better precision.
Explicit conversion to a Matrix
. Returns self
Return a single-column matrix from this vector
