TransForming matrices
To transpose a matrix
1. Select the appropriate Transpose Matrix command:
® 0
EH)
MATRIX MAKE TEN (if you want the conjugate transpose of a
complex matrix), or
® 0 (WiCB] OPERATIONS TRAN (if you want transposition without
conjugation).
2.
Enter or select the array you want to transpose.
3.
Press
(ENTER)
to transpose the matrix.
The first row of the original matrix is now the first column, the original
second row is now the second colmnn and so on.
To invert a square matrix
1. Press 0.
2.
Enter or select the array you want to invert.
3.
Press
(ENTER)
to transpose the matrix.
To change the dimensions of an array
1. Select the Redimension Array command.
0 (BCES) CREATE RDM
2.
Enter or select the array that you want to redimension.
3.
Enter a list containing tire new dimensions of the aixay:
{ roiv, colum n }.
4.
Press
(ENTER).
Elements from the original array are placed in row-major order into
the newly-dimensioned array. If there are fewer elements in the new
array than in the original one, the excess elements are dropped. If
there are more elements in the new array tlran in tire original one, the
missing elements are filled with zeros (or (0,0) if the array is complex).
For example, rdm(
1 2
_3 4
12 3 4
, {3,4 j) results in:
0 0 0 0
0 0 0 0
