Examples

data("act_pattern")

# Calculate the cosine similarity between an activation pattern and itself
similarity <- cossim(
x = act_pattern$signal,
y = act_pattern$signal
)

# Calculate the cosine similarity between a non-negative activation pattern and its negative
similarity <- cossim(
x = act_pattern$signal,
y = -act_pattern$signal
)
