PRINTF PRINTF Formated Output Function (C-Style)

Usage

Prints values to the output.  The general syntax for its use is

  printf(format,a1,a2,...)

Here format is the format string, which is a string that
controls the format of the output.  The values of the variables
a_i are substituted into the output as required.  It is
an error if there are not enough variables to satisfy the format
string.  Note that this printf command is not vectorized!  Each
variable must be a scalar.
