Read the equation
Row i specifies which source layers influence target layer i, with column j supplying the source. The constructor normalizes each nonzero row to sum to one. This convention determines the direction of matrix multiplication and should be kept distinct from a transpose convention.

| C_ij | Influence of source layer j on target i |
How it works
Read the definition from its right-hand expression to the quantity on the left. Its surrounding source records the intended input, state, or parameter context. Where the source leaves an operation unspecified, this page preserves that gap.
Assumptions & limits
Source recovery establishes that the expression appears in this record. Its mathematical validity, implementation behavior, and interpretation must be assessed separately. See the linked source and research notes for the checks available for this version.
