Generate synthetic temporal patterns for cluster signals — synthetic_time

Creates distinct temporal patterns for each cluster. Used internally by generate_synthetic_volume but exported for custom synthetic data generation.

Usage

synthetic_time_patterns(
  n_clusters,
  n_time,
  pattern_types = c("orthogonal", "harmonic", "random")
)

Arguments

n_clusters: Number of clusters/patterns to generate.
n_time: Number of time points.
pattern_types: Type of patterns: "orthogonal" (QR-decomposition for maximally distinct signals), "harmonic" (phase/frequency-shifted sinusoids), or "random" (random linear combinations of harmonics).

Value

A matrix of dimension n_clusters x n_time with one temporal pattern per row.
