Thread Subject: use the -v7.3 switch.

Hi all,

I am trying to save an m file using nohup (on the background) and I get this error

Warning: Variable 'P' cannot be saved to a MAT-file whose version is older than
7.3.
To save this variable, use the -v7.3 switch.

Can anyone tell me if this is because of the memory of the space I try to save or the vector size is very big?
I have MATLAB 2010a on Snow Leopard

Thanks

You said you are trying to save an "m file"
but the warning is about a "MAT-file". Which is it?

I'll assume it is a MAT-file and you are using the save command.
The documentation for save says:

When working on 64-bit platforms, you can have data items in your workspace
that occupy more than 2 GB. To save data of this size, you must use the HDF5-based
version of the MATLAB MAT-file. Use the –v7.3 option
to do this:
save -v7.3 myfile v1 v2
If you are running MATLAB on a 64-bit computer system and you attempt
to save a variable that is too large for a version 7 (or earlier) MAT-file,
that is, you save without using the -v7.3 option, MATLAB
skips that variable during the save operation and issues a warning message
to that effect.
If you are running MATLAB on a 32-bit computer system and attempt to
load a variable from a -v7.3 MAT-file that is too large
to fit in 32–bit address space, MATLAB skips that variable and issues
a warning message to that effect.

Without knowing anymore details, I'd say your variable "P" is too large.

In the future, a short code snippet would help us help you.
At the MATLAB prompt, try typing:

doc save

for more details.

Sorry for the m file thing. You are right, I am trying to save an mat file on a 64-bit platform. So you mean I can have it on my workspace but it will cause trouble when I save that since it is too big?
I will try save (filename,...,version) and see what happens.
Thanks for your help
