Syntax
Description
[data](#mw%5F42a5c9d4-6fb8-4d2f-8512-454c96e71bbc) = readall([ds](#mw%5F7cb0237a-a634-4fc7-ae14-7fed5140aa4f)) returns all the data contained in the label datastore specified byds.
If all the data in the datastore does not fit in memory, thenreadall returns an error.
Input Arguments
Output Arguments
Output data, returned as an _M_-by-2 cell array, cell array of categorical matrices, or a table.
| Datastore | Output Description |
|---|---|
| PixelLabelDatastore | Table with MiniBatchSize number of rows. For the last batch of data in the datastore,numObservations must be divisible by MiniBatchSize orread returns a partial batch containing all the remaining observations in the datastore. |
| boxLabelDatastore | _N_-by-2 cell matrix.N must be less than or equal toReadSize(ds). The first column must be a cell vector that contains bounding boxes. Each element in the cell vector contains_M_-by-4 matrices in the format [x,y,width,_height_].The second column must be a cell vector that contains the label names corresponding to each bounding box. Label names are represented as an_M_-by-1 categorical vector. |
