Data from the blockedPointCloudDatastore, returned as a cell
array of block data. The length of the cell array is equal to the value of the
ReadSize property of the
blockedPointCloudDatastore object. Each element of
b contains the data for a single block of
bpcds. The readall function returns the data
from each individual read operation such that the data can be concatenated
vertically.
The data type of this output is the same as the data type of the output of the
read function.
