How can i create and save to a filename that derives from my data?

x= 'a number from my data' (ex *117*)
y= 'another number from my data' (ex *00*)
q=['LOC1_2015_', *num2str(x)*,'_', *num2str(y)*,'_00_00000_CH1.mat']

q =

LOC1_2015_ *117*_ *00*_00_00000_CH1.mat

Now I want to create and save a file name with that name:

save('LOC1_2015_ *117*_ *00*_00_00000_CH1.mat')

Any ideas?

I'd use sprintf()

filename = sprintf('LOC1_2015_%2.2d_%2.2d_00_00000_CH1.mat', x, y)
save(filename);

but your way should work. What's the problem?

I want to write it in a script to run many data and save files with different names.

save('LOC1_2015_ 117_ 00_00_00000_CH1.mat') is written manualy. How can I automate it?

If I write

save('q') I ll have as a filename the variable q but what I want is the value/text of

q --> LOC1_2015_ 117_ 00_00_00000_CH1.mat to be saved as the filename.

Thank you for the responce

What I mean is how can I extract the value of a variable and use it as a filename?

(If we assume that q is the variable and LOC1_2015_ 117_ 00_00_00000_CH1.mat is the value of q)
