Creates a node; this function can be used together with qnsolve. It is possible to create either single-class nodes (where there is only one customer class), or multiple-class nodes (where the service time is given per-class). Furthermore, it is possible to specify load-dependent service times. String literals are case-insensitive, so for example "-/g/inf", "-/G/inf" and "-/g/INF" are all equivalent.

INPUTS

S

Mean service time.

• If S is a scalar, it is assumed to be a load-independent, class-independent service time.
• If S is a column vector, then S(c) is assumed to the the load-independent service time for class c customers.
• If S is a row vector, then S(n) is assumed to be the class-independent service time at the node, when there are n requests.
• Finally, if S is a two-dimensional matrix, then S(c,n) is assumed to be the class c service time when there are n requests at the node.

m

Number of identical servers at the node. Default is m=1.

s2

Squared coefficient of variation for the service time. Default is 1.0.

The returned struct Q should be considered opaque to the client.
