Calculates the rank-2k update of the upper or lower triangular component of a Hermitian 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
Matrix such that op(A) has dimensions N × K.
Matrix such that op(B) has the same dimensions as op(A).
Hermitian matrix.
C must have dimensions greater than or equal to N × N, where N is the number of rows in op(A). If C is an empty matrix, this node initializes C to be an N × N matrix with all elements set to 0.
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 A * BH and AH * B, where AH and BH represent conjugate transpose of A and B, respectively.
Default: 1+0i
Scalar that scales C.
Default: 1
Matrix of the same dimensions as C.
For the first N rows and N columns in the triangular component you select in matrix C type, zher2k returns the result of the following equation:
zher2k = alpha * op(A) * op(B) H + ( ) * op(B) * op(A)H + beta * C
where
op(A)H represents the conjugate transpose of op(A)
op(B)H represents the conjugate transpose of op(B)
represents the conjugate of alpha
For any remaining rows and columns, zher2k returns the element in C with the same index.
