Load file into parallel session
Part of filename common to all saved files being loaded.
pload(fileroot) loads the data from the files named
[fileroot num2str(labindex)] into the workers running a
communicating job. The files should have been created by the
psave command. The number of
workers should be the same as the number of files. The files should be accessible to
all the workers. Any codistributed arrays are reconstructed by this function. If
fileroot contains an extension, the character representation
labindex will be inserted before the extension. Thus,
pload('abc') attempts to load the file
abc1.mat on worker 1,
abc2.mat on worker
2, and so on.
Create three variables — one replicated, one variant, and one
codistributed. Then save the data. (This example works in a communicating job or in
pmode, but not in a
clear all; rep = speye(numlabs); var = magic(labindex); D = eye(numlabs,codistributor()); psave('threeThings');
This creates three files (
threeThings3.mat) in the
current working directory.
Clear the workspace on all the workers and confirm there are no variables.

Load the previously saved data into the workers. Confirm its presence.
