Okay, I've written a piece of code that creates several plots of some data. I would like to be able to create a distinct title for each plot in the for loop shown below. I would like the title to be something like "False Load vs. Time on Day XXX of Test 1.0". Where XXX is an integer number corresponding to the day of testing. Is there any way to do this?

Thanks in advance!

x = 1:1440; x = x./60;

y = 1:8;

for i = 1:length(sure);

    figure(i);
    plot(x,safals(:,i))
    title('False Load vs. Time on Day of Test 1.0');
    xlabel('Time of Day [hrs]');
    ylabel('False Load Power [Watts]');
    axis([0 24 0 2600]);
    hold;
end

在 MATLAB Online 中打开

Number=10; %the value you want to put on the title
title(['False Load vs. Time on Day ' num2str(Number) ' of Test 1.0'])

or use sprintf instead of num2str, the example I provided does string concatenation like this [string1 string2 string3 ...]

Thank you! This helped a lot. I've been trying the num2str function with little success until I noticed from your example that I forgot to insert the [] brackets. Duh! Thanks again!
