mask = sigroi2binmask(roilims)
converts roilims, a matrix of signal region-of-interest (ROI) limits,
to a binary sequence, mask, with true values
indicating samples that belong to regions of interest.
Consider a two-column matrix of beginning and end samples of four possible regions of interest of a signal. Convert the ROI limits to a logical sequence and display the sequence.
roilims — Region-of-interest limits two-column matrix of positive integers
Region-of-interest limits, specified as a two-column matrix of positive integers. The
ith row of roilims contains nondecreasing
indices corresponding to the beginning and end samples of the ith
region of interest of a signal.
Example: [5 8; 12 20; 18 25] specifies a two-column region-of-interest
matrix with three regions.
len — Output sequence length max(roilims(:,2)) (default) | integer scalar
Output sequence length, specified as an integer scalar. Regions with indices larger
than len are ignored or truncated. If len is
greater than max(roilims(:,2)), then sigroi2binmask pads
mask with false values.
