Dear all,
I am having a problem with Matlab and I don't know how to solve it, I tried to search for the error and I couldn't find any solution, can you help me please ?
I am getting the following message when I try to save a huge image 5003 x 49597, using Pcolor, and it is not saving my image.
matlab warning: Variable 'hgS_070000' cannot be saved to a MAT-file whose version is older than 7.3. To save this variable, use the -v7.3 switch. Skipping... > In hgsave at 268 In general\private\saveasfig at 7 In saveas at 126 In loading_whole_summer2009 at 24 (this is the function name I have created)
I am using a desktop with a 16GB of RAM and 1TB of hard disk, and I am running only Matlab. Is there a way to optimize the memory or can you explain to me what does it mean the 'use the -v7.3 switch.'
thanking you in advance,

Instead of saveas, use:
hgsave(1, ['C:\users\lefou\desktop\back/' jd '/' Outputname '.fig'], '-v7.3');
From the documentation on hgsave:
hgsave(...,'-v7.3') saves the FIG-file in a format that can be loaded only by MATLAB versions 7.3 and above. This format, based on HDF5 files, is intended for saving FIG-files larger than 2 GB.

i am trying to save a figure in matlab.
i gave this command.
hgsave(1, ['N:\DL_Diag\hmld\DSM-DI Team\Arun\SCRCE_Mustang\back/' jd '/' NHA_Linx_3539 '.fig'], '-v7.3');

hgsave(1, 'N:\DL_Diag\hmld\DSM-DI Team\Arun\SCRCE_Mustang\back\NHA_Linx_3539.fig', '-v7.3');

type 'help save' or 'doc save' for options of save() command. '-v7.3' is to allow support for data items greater than or equal to 2GB.

No. It looks like you want to save the image to a .fig file. It shouldn't cause memory problem. You could clear all the variable before saveas(). Are you sure you have the right file name? You could also try print() command.
