  The MAT statement lets you implicitly create  and  manipulate  one-  and
  two-dimensional  arrays.  You can use the MAT statement to assign values
  to array elements, or to redimension  a  previously  dimensioned  array.
  You   can   also   perform   matrix   arithmetic   operations   such  as
  multiplication, addition, and subtraction, and other  matrix  operations
  such as transposing and inverting matrices.

  For information on the graphics MAT PLOT or MAT...POINT statements, type
  either  "Graphics  MAT_PLOT"  or  "Graphics  MAT...POINT"  at  the  help
  facility prompt "Topic?".

  Examples:

  MAT First_array = ZER
  MAT String_array = NUL$
  MAT A = B + C
  MAT C = (55.2) * First_array
