Therefore, you must specify version as "-v7" or "-v7. If a variable already exists in a MAT-file, then save overwrites it with the value in the workspace. To append to a Version 6 MAT-file, you must also specify version as "-v6". The existing file must be a MAT-file Version 7 default or 7. Command form requires fewer special characters. You do not need to type parentheses or enclose the input in single or double quotes.

The problem is that when you save a. For example, suppose there is data in the input buffer for obj. In this case, there are three separate expression arguments:.

Help Center Help Center. You can save and load parts of variables directly in MAT-files without loading them into memory using the matfile function. The primary advantage of using the matfile function over the load or save functions is that you can process parts of very large data sets that are otherwise too large to fit in memory. When working with these large variables, read and write as much data into memory as possible at a time. Otherwise, repeated file access can negatively impact the performance of your code. This example shows how to load, modify, and save part of a variable in an existing MAT-file using the matfile function.
