Highlights

  • Reuse the effective input/output delay matrix across all frequency points evaluated by System.FreqResponsePointwise.
  • Keep delayed sweep allocations constant as the frequency grid grows instead of rebuilding a slice and dense-matrix header for every point.
  • Construct the transfer-function fallback delay matrix lazily, only if a state-space solve fails at an individual frequency.
  • Preserve the existing bit-identical single-point arithmetic contract; the optimization changes allocation ownership, not per-frequency numerical operations.

Compatibility notes

  • This release changes no public API or caller workflow.
  • Existing FreqResponsePointwise results and fallback behavior remain unchanged.
  • The module path remains github.com/jamestjsp/controlsys.
