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.

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

text = INIT( APPENDIX("Table23A"), X, A, n, m)

ALLOCATE

resize

ALLOCATE( B, 10, 20) ! 10 x 20 matrix

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

X = EXP(Y)

binary OP

works element-wise, like Scalars

X = 1.23 * Y

column index of a left-hand side matrix

A = $C

1 2 3
1 2 3
1 2 3

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

inlineLoop index

trace = +(A( $1 , $1))

ALIAS

named sub-vector

ALIAS(A,2, vec,3)

2 3 4

named sub-matrix

ALIAS(A,2, mtx,-2,-3)

2 3 4
5 6 7

InlineLoop

set or reduce arrays or sub-arrays in 1 line

trace_max = MAX( A( $1, $1) )

LEN_TRIM(A)

trimmed (linear) length

L = LEN_TRIM(A)

TRIM(A)

(linear) length

L = LEN(A)
