DIMENSION: Define a numerical array

• DIMENSION vector(elements), matrix(rows, columns)

• specifies 1-dimensional vectors and 2-dimensional matrices
• elements, rows and columns must be known at compile time, like:
  • integer

    constants

    , like
    • DIMENSION v1(100), v2(20), m1(20,100), v3(33)

  • predefined at compile time

    , like
    • REAL, PARAMETER :: elements=100 ! defines the

      symbolic constant

      elements
    • REAL :: rows=20 ! predefines the scalar

      variable

      rows
    • DATA columns/50/ ! predefines the scalar

      variable

      columns
• ⇒ Define symbolic names to be of real data type
