MAT ASSIGNMENT (TRANSPOSE FUNCTION)
This statement allows you to replace the elements of one array with the matrix
transpose of another array. The syntax of the statement is as shown:
MAT array-name [(rows, columns)]
=
TRN (array-name)
where:
all parameters in the statement are the same as those for other MAT assignment
statements, and TRN specifies the transpose function.
The transpose matrix of the array specified to the right of the equal sign is assigned
to the array specified to the left of the equal sign. The values in column y of one
array become the values in row y of the other array.
If redimension specifications follow the array name to the left of the equal sign, the
truncated integer portion of each expression value in rows, columns is used to redi-
mension the array before values are assigned to it.
Notes About MAT (Transpose Function)
• Both arrays specified must be two-dimensional, and the number of rows in each
array must be equal to the number of columns in the other (after redimensioning,
if any). and they must be the same type (character or numeric).
• The same array cannot be used on both sides of the equal sign. This will cause
incorrect results.
• If the redimension specifications are included, the rules under Redimensioning
Arrays, Chapter 3, must be followed.
