Save Function does not work

I am using an online server to operate matlab and when I am trying to save on the specific directory the following happens. Does anyone have any idea how to fix this, thanks.

save('plot.mat','pcaplt')
Error using save
Error closing file /lustre/home/zcbemav/plot.mat.
The file may be corrupt.

save('plot.mat','pcaplt','-v7')
Error using save
Error closing file /lustre/home/zcbemav/plot.mat.
The file may be corrupt.

save('plot.mat','pcaplt','-v7.3')

The file may be corrupt.

[Sai Sri Pathuri]

Can you provide information about pcaplt? It may hep.

[Walter Roberson]

Error using save

Error closing file /lustre/home/zcbemav/plot.mat.

The file may be corrupt.

That can be caused by running out of disk space.

Answer 1

[Guillaume]

If you look at the error message #031 in the hdf save, you can clearly see the problem:

  #031: H5FDsec2.c line 822 in H5FD_sec2_write(): file write failed: time = Tue Jul 30 16:37:53 2019
 [..] error message = 'Disk quota exceeded', [..]

The file is too big for the amount of disk space you've been allocated.
