Slides template across x, computing the centred Pearson-style
correlation per offset. Returns indices and correlation values
meeting threshold.
Usage
morie_dsp_template_match(x, template, threshold = 0.7)
Arguments
- x
Numeric vector.
- template
Numeric vector (shorter than x).
- threshold
Minimum correlation. Default 0.7.
Value
List with indices (1-based) and correlations.
