Thread Subject: variables in titles ??

Let's set the variable number=5.

If I write underneath a plot command "title(number)"
The title ofmy plot is 5

Now what if I want to do something like "title('plot with frequency set to equal' number)"

The overall goal is to have the title being "Plot with frequency = number , and wavelength = number2 "

where number and number2 are predefined variables.

Any ideas ??

Use sprintf to format your title string -

str = sprintf('Plot with frequency = %f , and wavelength = %f',number,number2);
title(str);

How about something like

str=sprintf('Plot with frequency = %d and wavelength = %d', number1, number2);

title(str)



You then need to review the different ways to format the output, eg %d,%6.3f etc

That works very well!

But I guess I can't incporporate latex into my title then ??

usually I do title('\frac{1}{2}','Interpreter','latex') and the fraction enters my title, but with this method it seems that the latex doesn't come out or I get an error message.

Use Math mode in laTex
> title('$\frac{1}{2}$','Interpreter','latex')

Thanks alot it was a great help, can we do something similar with save as command ...??
I am analyzing data for every month with multiple plots,so, every time I have to change month name in my save option before executing my code.So, is there any way I can set variable for that and just vary that.I will appreciate any kind of help.
Thanks in advance.

Dear Aman,

Do you mean the SAVEAS command? Or with "save" as command?
What is "change month name in my save option"?

You can use SPRINTF to create a file name for the SAVE or SAVEAS commands.
