I'd like to create a textbox annotation in a figure called "figure1", but it always gives me an error saying that there are too many input arguments for "annotation". Here's what I do:

annotation(figure1,'textbox',[0.2726 0.638 0.1111 0.05249],...
        'String',{'Slope = Hp'},...
        'HorizontalAlignment','center',...
        'FontSize',14,...
        'FitBoxToText','off');

What's wrong with this?

It worked for me. You did do this before you called it, didn't you:

figure1 = figure;

Run this:

figure1 = figure;
annotation(figure1,'textbox',[0.2726 0.638 0.1111 0.05249],...
        'String',{'Slope = Hp'},...
        'HorizontalAlignment','center',...
        'FontSize',14,...
        'FitBoxToText','off');

It gives no errors or warnings whatsoever. Is it possible you redefined annotation() with your own function? What does this say:

>> which -all annotation

Thanks Image Analyst...I had some toolbox installed which contained a function "annotation". So I renamed the function and now everything works as expected.
