- (local)Array of sizelds.On entry, a matrix already in Schur form.
- (local)On entry, the leading dimension of the arrays; unchanged on exit.
- (local)On entry, the order of the matrixS; unchanged on exit.
- (local)Array of size 2*j. The work buffer required by thefunction.
- (local)Set, if the input matrix had an odd number of real eigenvalues and things could not be paired or if the input matrixSwas not originally in Schur form. 0 indicates successful completion.
- On exit, the diagonal blocks ofShave been rewritten to pair the eigenvalues. The resulting matrix is no longer similar to the input.
- Work buffer.
