Data Conversion Rules
B-9
int32
A 1-by-1 int32 matrix
converts to a
VARIANT of
type
VT_I4. A complex
1-by-1
int32 matrix
converts to a
VARIANT of
type
VT_DISPATCH.
A multidimensional
int32 matrix converts
to a
VARIANT of type
VT_I4|VT_ARRAY. A
complex
multidimensional
int32 matrix converts
to a
VARIANT of type
VT_DISPATCH.
Complex arrays are
passed to and from
compiled
M-functions using
the
MWComplex
class. See “Class
MWComplex” on
page D-23.)
