strings in a loop

Hi all,
I made up some code to put a piece of text in a figure. But at the moment it only supports 2 values. I need it to be in a loop, so I can get the values with Frr(i).
text( 0.97, 0.93, ...
[ '\fontsize{8}\color{blue}' ...
num2str(Frr(1)) ' Hz, ' num2str( Prr(1)), 10, ...
num2str(Frr(2)) ' Hz, ' num2str( Prr(2)), 10, ...
'EdgeColor','black', 'HorizontalAlignment', 'right', 'VerticalAlignment', 'top', 'Margin', 3, 'Units', 'normalized' );
I have been trying different things, like making strings and concatenating them together, but it becomes one long string.
I hope someone can help me.
Thanks in advance,
Gr. Sven
btw: the '10' in the code is the ascii code for a new line...

This is really a question about how to get a line break in TeX or LaTex.

Sven,
In most Matlab functions that display text, you can pass a cell array of strings to accomplish new lines. The example below does this for the two case example you gave.
text( 0.97, 0.93, ...
{['\fontsize{8}\color{blue}' num2str(Frr(1)) ' Hz, ' num2str( Prr(1))], ...
['\fontsize{8}\color{blue}' num2str(Frr(2)) ' Hz, ' num2str( Prr(2))]}, ...
'EdgeColor','black', 'HorizontalAlignment', 'right', ...
'VerticalAlignment', 'top', 'Margin', 3, 'Units', 'normalized' );
To put this in a loop, try something like this.
Frr = randi(10,10,1);
Prr = randi(10,10,1);
strFun = @(x, y) ['\fontsize{8}\color{blue}' num2str(x) ' Hz, ' num2str(y)]
strCell = cell(size(Frr));
for i = 1:numel(Frr)
strCell{i} = strFun(Frr(i), Prr(i));
end
text( 0.97, 0.93, strCell, ...
'EdgeColor','black', 'HorizontalAlignment', 'right', ...
'VerticalAlignment', 'top', 'Margin', 3, 'Units', 'normalized' );
