title, interpreter latex and num2str

Question

0 个投票

Hi,

I want to use 'interpreter','latex' in a title that contain the function num2str and I cannot make it work.

This works: title('$\alpha$','interpreter','LaTex')

But this does not: title(['$\alpha$: ',num2str(x),'$\%$'],'interpreter','latex')

Any idea how can I solve this?

Thank you

You could try

title( sprintf('$\\alpha$: %f$\\%%$', x) )

Notice the doubling of the \ and the % as those have special meaning is sprintf.

I had to guess about the numeric format you wanted.

It works for me (in R2015b), at least as I expect it to work.

Attach your plot images so we can see what the problem is. (Use the floppy disk icon on the plot GUI to save the plot as .png, then in the text box here, use the brown-framed green landscape icon, and complete both the ‘Choose file’ and ‘Insert image’ steps.) I’m describing that in detail for a reason. Many people do not do all that and then wonder why their image or file did not upload.
