ROT
ROT[x,y,c,s]
applies a Givens rotation {{c,s},{-Conjugate[s],c}} to the vectors x and y.
更多信息和选项
- To use ROT, you first need to load the BLAS Package using Needs["LinearAlgebra`BLAS`"].
- The following arguments must be given:
-
x input/output symbol vector; the symbol value is modified in place y input/output symbol vector; the symbol value is modified in place c input expression real-valued scalar s input expression scalar - ROT[x,y,c,s] is equivalent to {x,y}={{c,s},{-Conjugate[s],c}}.{x,y} where x and y are row vectors.
- The vector arguments must be of the same length.

ROT[x,y,c,s] is equivalent to {x,y}={{c,s},{-Conjugate[s],c}}.{x,y}:
Possible Issues (4)
If the first or second argument are not symbols, an error message is issued:
If the first or second argument are not initialized, an error message is issued:
The third argument c should be real.
The third and fourth arguments 
and 
should satisfy the relation 
to be a true Givens rotation. This condition is not checked.
