Using a MAT-File Object to Save a Variable in Chunks

I need to save a 50GB string variable to a MAT file. I have noticed that when I use the save command, memory usage is increased temporarily, perhaps while making a copy of the variable. To minimize the peak amount of memory I need, I’m going to break up the variable and try to save it in chunks using the MAT file object, which I have not used before.

  • matfile
  • save
