extract_cues.RdThis function is used to extract multiple sub-samples of data from a vector or matrix.
extract_cues(x, sampling_rate, cues, len)
| x | is a vector or matrix of measurements. If x is a matrix, each column is treated as a separate measurement vector. |
|---|---|
| sampling_rate | is the sampling rate in Hz of the data in x. |
| cues | defines the start time in seconds of the intervals to be extracted from x. |
| len | is the length of the interval to extract in seconds. This should be a scalar. |
A list with 2 elements:
X: A matrix containing sub-samples of x. If x is a vector, X has as many columns as there are cues, i.e., each cue generates a column of X. If x is a pxm matrix, X will be a qxmxn matrix where n is the size of cues and q is the length of the interval requested, i.e., round(sampling_rate*len) samples.
cues: The list of cues actually used. cues that require data outside of x are rejected.
Output sampling rate is the same as the input sampling rate.
