Transforming Matrices
To transpose a matrix:
1. Enter the matrix onto the stack.
2. Press
(MTH1
M
h
T R M F i K E T R H to transpose the matrix. The
first row of the original matrix is now the first column, the original
second row is now the second column and so forth. This computes
the conjugate transpose of complex matrices.
To inwert a square matrix:
14
1. Enter the square matrix.
2. Press
(lTx\
to invert the matrix. Note that matrix inversion can
produce erroneous results if you are using ilhconditioned matrices.
See “Ill-Conditioned and Singular Matrices” on page 14-16.
To change the dimensions of an array:
1. Enter the array onto the stack.
2. Enter a list containing the new dimensions of the array:
■ C
rows columns

3. Press ( M T H ) M
h
T R M A K E R D M to redimension the array.
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 than in the original one,
the missing elements are filled with zeros (or < 0 . 0 > if the array is
complex).
