A list that contains all information about the handled sfa-structure |
arg |
Input data, each column a different variable |
step |
Specifies the current SFA step. Must be given in the right sequence:

list sfaList
taken from the input, with new information added to this list.
Among the new items are:
avg0 |
mean vector in input space |
avg1 |
mean vector in expanded space |
W0 |
(ppRange x ppRange)-matrix, the whitening matrix for the input data |
C |
covariance matrix of the time-diff of expanded and sphered data |
SF |
(sfaRange x sfaRange)-matrix with rows which contain the directions in expanded space with slow signals. The rows are sorted acc. to increasing eigenvalues of C |
