Creation of a Connectivity Matrix with a Link Table
A links table can easily be used to construct a connectivity
matrix, a core element for measuring accessibility. It can
be achieved by using a simple algorithm:
- The values of all the cells Cij in
the connectivity matrix C are set to 0. The default assumption
that nodes are not linked.
- For each record of the links table, the link becomes
a connection (value of 1).
- For each record of the links table, an inverted connection
is created if the link is bi-directional (not a one way).
