Calculates the rank-2k update of the upper or lower triangular component of a symmetric matrix.
Operation this node performs on A and B.
Name | Value | Description |
---|---|---|
Direct | 0 | op(A) = A and op(B) = B |
Conjugated and Transposed | 1 | op(A) = conjugate transpose of A and op(B) = conjugate transpose of B |
Transposed | 2 | op(A) = transpose of A and op(B) = transpose of B |
Default: Direct
Triangular component of C this node uses for the calculation.
Name | Value | Description |
---|---|---|
Lower Triangular | 2 | This node uses the lower triangular component of C for the calculation. |
Upper Triangular | 3 | This node uses the upper triangular component of C for the calculation. |
Default: Upper Triangular
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
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.
Default: No error
Scalar that scales op(A) * op(B)^{T} + op(B) * op(A)^{T}, where op(A)^{T} and op(B)^{T} represent op(A) and op(B) transposed, respectively.
This input accepts the following data types:
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.
Matrix of the same dimensions as C.
For the elements in the first N rows and N columns of the triangular component you select in matrix C type, dsyr2k returns the result of the following equation:
dsyr2k = alpha * op(A) * op(B)^{T} + alpha * op(B) * op(A)^{T} + beta * C
For any other elements, dsyr2k 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.
Matrix of the same dimensions as C.
For the elements in the first N rows and N columns of the triangular component you select in matrix C type, zsyr2k returns the result of the following equation:
zsyr2k = alpha * op(A) * op(B)^{T} + alpha * op(B) * op(A)^{T} + beta * C
For any other elements, zsyr2k 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.
