the superscript in the textbox in the figure?

How can I put (degree) the degree of temperature Celsius in the text box inside the figure? ex: C to the power (Celsius)

1. Right click, then Select latex mode 2. input $^{\circ}$C 3. done

Answer 1

[Image Analyst]

You can do this:

plot(1:10);
str = sprintf('30 %cC', 176); % ASCII 176 looks like the degree symbol.
text(2,2,str);

[Salaheddin Hosseinzadeh]

Wow! Is this really how you're doing it?! sprintf?!

text(2,2,'30^c')

MATLAB knows a little bit of LaTex, he is very cleaver! believe me! lol

[Image Analyst]

Yes, but I don't know LaTex. I don't need to since modern work processors have all the formatting I need and I'm not required to know LaTex, though I know there are still some people who still use it.

[Salaheddin Hosseinzadeh]

LOL! I still do, though I don't recommend it. But I prefer it to Microsoft Word when it comes to write hundreds of pages, and I'm gonna stick to it, unless you kindly suggest me a better one.

Tnx

It’s very well hidden in the documentation. In the online documentation it’s under String. That reveals:

\circ   º

The rest of the special TeX characters are there as well.

Answer 3

[Salaheddin Hosseinzadeh]

As I remember MATLAB understand a little bit of Latex! lol

If you've ever worked with Latex which is just like writing in a linear form try this

legend('C^{Celcious}') or title or xlable or ...

or

title('C^o')

if you want to have Celsius sign

Let me know about the results plz.

Good Luck!

[Mary Jon]

Thank u Hosseinzadeh

I want write C^o in the text box (superscript)in the figure (near the curve )only not as legend or title,

your answer is as legend or title,

[Salaheddin Hosseinzadeh]

You can apply the same format to text, legend, disp, display, labelx labely title and similar functions that accept strings generally

Answer 4

[Salaheddin Hosseinzadeh]

If you have a variable then you can concatenate the string simply

x=30;
title([num2str(x),'^c']) or legend or text or xlable or ...

Be lazy and go with the easy one! lol

Good Luck!

[Mary Jon]

Mr. Hosseinzadeh

 your code put title in the top of figure (30^c)

the answer of (Image Analyst )is excellent.

Answer 5

[Salaheddin Hosseinzadeh]

I don't know what version of MATLAB you are using! But the following code resulted as such on my PC with 2012a and it's really easy to use this notation! You can see the image as well!

figure
text(0.1,0.1,'Hello^{World}')
text(.3,.3,'trying_{subscript}')
text(.6,.6,'trying_{subscript}^{power}')

[Salaheddin Hosseinzadeh]

I hope the pics would be clear, it ws the first time I posted pics! I thought one can click to see the full size image!

[Mary Jon]

Thank u Salaheddin Hosseinzadeh

Wow,matlab is very good tool,really.

I want to learn not every thing, but more thing on it

[Image Analyst]

You CAN click on the image to bring it up full size. At least using Firefox you can.

Answer 6

[Salaheddin Hosseinzadeh]

Another instance when you have numbers to deal with!

   >> x=30

x =

      30

>> figure
>> text(.1,.1,[num2str(x),'^c'])
>>
