Read data specified by index from pixelLabelImageDatastore


data = readByIndex(pximds,ind)
[data,info] = readByIndex(pximds,ind)


data = readByIndex(pximds,ind) returns a subset of observations from a pixel label image datastore, pximds. The desired observations are specified by indices, ind.

[data,info] = readByIndex(pximds,ind) also returns information about the observations, including metadata, in info.
