TRN
The TRN function returns an array whose elements are the exchanged rows
and columns of a specified array. Both arrays must be the same type. It
has the form
MAT num_array1 = TRN( num_array2 )
where the rows of num_array1 are the columns of num_array2 , and the
columns of num_array1 are the rows of num_array2 . num_array1 is
dimensioned ( n , m ) and num_array2 is dimensioned ( m , n ).
This function is used with the MAT = statement, with two-dimensional
arrays.
Syntax
TRN( array )
Parameters
array Structured collection of variables of the same type.
The structure is determined when the array is declared.
Examples
10 DIM A(4,3),B(3,4)
.

.
80 MAT A = TRN(B)
If B is
8 5 7 3
0 2 9 1
4 6 0 5
then A is
8 0 4
5 2 6
7 9 0
3 1 5
