</span><br><span class=help>% <span class=help_field>Description:</span></span><br><span class=help>% It loads data files from given directory DirName and
</span><br><span class=help>% merges them to one labeled data file. The individual files
</span><br><span class=help>% are assumed to contain the field X [dim x num_data].
</span><br><span class=help>% The file names have to have the following format
</span><br><span class=help>% name_xxx.mat ('_' can be omitted), where xxx denotes an
</span><br><span class=help>% integer which is used to label the data X from the given
</span><br><span class=help>% file. The OutputFile contains item X [dim x num_all_data]
</span><br><span class=help>% with all merged data and vector of labels y [1 x num_all_data].
</span><br><span class=help>%
</span><br><span class=help>% <span class=help_field>Input:</span></span><br><span class=help>% DirName [string] Input directory.
</span><br><span class=help>% OutputFile [string] Output data file.
</span><br><span class=help>%
</span><br><span class=help>% <span class=help_field>Output:</span></span><br><span class=help>% file OutputFile with items:
</span><br><span class=help>% X [dim x num_all_data] Data matrix.
</span><br><span class=help>% y [1 x num_all_data] Labels of data.
