 Matrix m,
 Matrix lambda,
 Matrix sigma,
 Matrix cap)

Computes cache miss metrics, optionally under per-list storage cost caps.

Parameters:

gamma - Cache access factors (n x h).

m - Cache capacity vector (1 x h).

lambda - Arrival rates per user per item (u x n).

sigma - Item storage costs (sizes); null or empty for none.

cap - Per-list storage cost caps; null or empty for none.

Returns:

the miss metrics.
