Single transition operators, spanning the space of matrices of the specified dimension. The set is returned as a cell array of sparse matrices using serpentine indexing where the position in the cell array maps in the following way to the location of the single non-zero: (1) (3) (6) (10) (2) (5) (9) (13) (4) (8) (12) (15) (7) (11) (14) (16) and likewise for larger matrices.
Syntax
A=sin_tran(dim)
Parameters
dim - dimension of the matrices
Outputs
A - a cell array of matrices, structured
as described above; matrices are re-
turned as complex to avoid expensive
reallocations later
Examples
See examples in the Spinach distribution relevant to this function.
