1 |
op(B) = conjugate transpose of
B

Default:
Direct

Default:
Direct
A
Matrix such that op(A) is an
M
×
K
matrix.
This input accepts the following data types:
-
2D array of double-precision, floating-point numbers
-
2D array of complex double-precision, floating-point numbers
B
Matrix such that op(B) is a
K
×
N
matrix.
This input accepts the following data types:
-
2D array of double-precision, floating-point numbers
-
2D array of complex double-precision, floating-point numbers
C
Matrix whose dimensions are greater than or equal to
M
×
N. If
C
is an empty matrix, this node initializes
C
to be an
M
×
N
matrix with all elements set to 0.
This input accepts the following data types:
-
2D array of double-precision, floating-point numbers
-
2D array of complex double-precision, floating-point numbers
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Many nodes provide an
error in
input and an
error out
output so that the node can respond to and communicate errors that occur while code is running. The value of
error in
specifies whether an error occurred before the node runs. Most nodes respond to values of
error in
in a standard, predictable way.
error in
does not contain an error
|
error in
contains an error
|
|
|
If no error occurred before the node runs, the node begins execution normally.
If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as
error out.
|
If an error occurred before the node runs, the node does not execute. Instead, it returns the
error in
value as
error out.

Default:
No error
alpha
Scalar that scales op(A) * op(B).
This input accepts the following data types:
-
Double-precision, floating-point numbers
-
Complex double-precision, floating-point numbers
Default:
The default value is 1 if
alpha
is a double-precision, floating-point number. The default value is 1+0i if
alpha
is a complex double-precision, floating-point number.
beta
Scalar that scales
C.
This input accepts the following data types:
-
Double-precision, floating-point number
-
Complex double-precision, floating-point numbers
Default:
The default value is 1 if
beta
is a double-precision, floating-point number. The default value is 1+0i if
beta
is a complex double-precision, floating-point number.
dgemm
Matrix of the same dimensions as
C.
For elements of the first
M
rows and
N
columns,
dgemm
returns the result of
alpha
* op(A) * op(B) +
beta
*
C. For any remaining elements,
dgemm
returns the value of the element in
C
with the same index.
This output is available only if you wire a 2D array of double-precision, floating-point numbers to
A,
B, or
C.
zgemm
Matrix of the same dimensions as
C.
For elements of the first
M
rows and
N
columns,
zgemm
returns the result of
alpha
* op(A) * op(B) +
beta
*
C. For any remaining elements,
zgemm
returns the value of the element in
C
with the same index.
This output is available only if you wire a 2D array of complex double-precision, floating-point numbers to
A,
B, or
C.
error out

The node produces this output according to standard error behavior.
Many nodes provide an
error in

error out
output so that the node can respond to and communicate errors that occur while code is running. The value of
