Arrays: Vectors and Matrices


HicEst knows 1- or 2-dimensional rectangular arrays as vectors (1 row, n columns) or m x n matrices. Higher order array can be realized with ALIAS.

use for example and result
REAL declaration
  • REAL :: n=3, X(n), A(n,n)
DIMENSION declaration
  • Y(3), B(3,3)
DATA initialization
  • DATA X/1.1, -9, 1.234E6/
APPENDIX uncompiled data storage at end of script
ALLOCATE resize
= set an array
A = 12.3
12.3 12.3 12.3
12.3 12.3 12.3
12.3 12.3 12.3
>< SWAP array(-elements)
  • A >< B
( ) array element
  • Y(m) = B(m, n)
unary OP apply OP to all elements
binary OP works element-wise, like Scalars
  • X = 1.23 * Y
$C column index of a left-hand side matrix
A = $C
1 2 3
1 2 3
1 2 3
$R row index of a left-hand side matrix
A = $R
1 1 1
2 2 2
3 3 3
$ linear index of left-hand side matrix
A = $
1 2 3
4 5 6
7 8 9
$1 inlineLoop index
trace = +(A( $1 , $1)) 15
ALIAS named sub-vector
ALIAS(A,2, vec,3) vec: (2,3,4)
named sub-matrix
ALIAS(A,2, mtx,-2,-3) mtx:
2 3 4
5 6 7
InlineLoop set or reduce arrays or sub-arrays in 1 line
trace_max = MAX( A( $1, $1) ) 9
LEN_TRIM(A) trimmed (linear) length
L = LEN_TRIM(A) 9
TRIM(A) (linear) length
L = LEN(A) 9
