index in safe-title

I would like to define my file with the title, so that includes the according index. I tried:

saveas(gcf,'title_t{n}','jpeg')
saveas(gcf,'title', t{n},'jpeg')

Either wont work - is there a way?

Thanks in advance!

Try:

str = "title_" + t{n}
saveas(gcf,str,'jpeg')

This will attempt to convert t{n} into a string and concatenate the string "title_" and that newly created string. I've defined it as a separate variable so you can see what it looks like. If this doesn't do what you want, show us the value of str that is displayed when you run this code and describe how it differs from how you want it to look.

saveas(gcf,[title_t{n},'jpeg'])

Hi,

thanks for your response.

Unfortunately that does not work for me:

Undefined variable title_t.

saveas(gcf,['title_' t{n}],'jpeg'])

Hey Walter!

Either you used one bracket too much or too little. I tried:

saveas(gcf,['title_' t{n}],'jpeg')

which gives me:

Error using saveas (line 96)

Invalid filename.

What datatype is t{n} ? If it is numeric then

filename = sprintf('title_%g.jpg', t{n});
saveas(gcf, filename, 'jpeg')
