save in .mat

Hi i have problem when i saved matrix in name (Ybustotal) in 3D (609*609*1024) the matlab gives me this massage Warning: Variable 'Ybustotal' cannot be saved to a MAT-file whose version is older than 7.3. To save this variable, use the -v7.3 switch. Skipping...

i am using MATLAB R2014a can any one help me with this problem

thank you

Apparently, it wants you to use the syntax:

save(filename,'Ybustotal','-v7.3')

thank you for answring me what do you mean in filename i used the name of M-file that i am working on it .it doesn't work second i used any name of matrix to save on it . so i used save(Ybustotal,'Ybustotal','-v7.3')

it gives me Error using save Argument must contain a string.

save('NameOfMatFile.mat', 'Ybustotal', '-v7.3')

If you have a current save command like

save MyMat YBustotal

then just add -v7.3

save MyMat YBustotal -v7.3

and if you have not specified the variable names and want YBustotal.mat to be your output file that stores all variables in your current workspace, then

save YBustotal -v7.3

My pleasure.

To save it as the same name as the matrix, do this:

save('Ybustotal.mat','Ybustotal','-v7.3')

You need to use the .mat extension to specify the filename, otherwise MATLAB interprets it as a variable, and saves it to the default file name 'matlab.mat'. All save function arguments must be strings.
