Hello everyone, I'm trying to figure out to change line for my instruction. I use sprintf to display text on the plot. However, I have no idea how to change line for my instruction. Here's my code for instruction page. Please let me know what should I change. Thanks a lot!!
fig=figure;
set(fig, 'Position', get(0,'Screensize')); % Maximize figure.
instruct=sprintf('Put your right index finger on P and put your left index finger on Q.You will see the target(★) either left or right square.If the target is on the right, please press P. If the target present on the left, please press Q.Please response as soon as you can.');
textToDisplay = text(0,0.5,instruct); %display text in the graph
set(textToDisplay,'Fontsize', 15,'Color','k') %set the fontsize and color of 'x'
axis off
pause
clf

By "change line," do you mean add a line break? Assuming this is the case, you can add the regular expression '\n' to your string.
For example:
instruct = sprintf('My instruction on \ntwo lines')
produces:
instruct =
My instruction on
two lines
Note that the sprintf command immediate recognizes '\n' and inserts a line break, even though there is not a space between that and the word 'two'.
