Adding Superscript to a string

Hi guys i am new to forums.

my issue is as follows. I have a string to which other strings are concatenated. I want some of them to be in superscript. code is as follows

for i = 1:(length(p)-1)
    str = [str,num2str(p(i)), 'X' , (num2str(length(p) -i)), ' + '];
end

i want the portion (num2str(length(p) -i)) to be in superscript but it seems to be posing constant problem as i cannot use the 'abc^{def]' to simply put it in superscript.

any ideas?

Strings are vectors of type char. So they cannot have any superscript properties, because the appearance of the string is controlled by the interpreter. Therefore it matters, where this string should appear.

While the creation and the contents of the string does not matter, it is required to show us the the command you use to display the string.

I use the gtext() command to display the results on to a graph

gtext(str);

Try experimenting with

str = [str, num2str(p(i)), 'X\textsuperscript{', num2str(length(p) -i), '} + '];

Nope it just displays the whole thing inside the quotes. including \textsuperscript.

however it gives me a warning

Warning: Unable to interpret TeX string "\textsuperscript{3} + -7.5235X\textsuperscript{2} + 2.5532X\textsuperscript{1} + "

   str = [str, num2str(p(i)), 'X^{', num2str(length(p) -i), '} + '];

That fixes the problem Thank you walter you gave me the inspiration :D

@Ali your method worked for me. Thanks!
