complexMatrix
Returns a real matrix in which each element is the real portion of the
corresponding element of a
complexMatrix
imag
complexMatrix
Returns a real matrix in which each element is the imaginary portion of
the corresponding element of a
complexMatrix
abs
matrix
Returns a real matrix in which each element is either the absolute value
of the corresponding element of a real
matrix
or the magnitude
(modulus) of the corresponding element of a complex
matrix
angle
complexMatrix
Returns a real matrix in which each element is either
0
if the element of
complexMatrix
is real or the polar angle if the element of
complexMatrix
is complex; the polar angles are calculated as
