I have some code that works out the y value of the first point on my graph where x>6. This is the 'failure' point.
figure
plot(x,y), hold all
failure=find(x>6,1);
I want to the display whatever this y_value is in a message box on the figure. I don't understand how I can get it to display the number that 'failure=find(x>6,1);' creates.
If I did msgbox('failure') it would just display the word 'failure' in the box, not the number. Any ideas?

msgbox(sprintf('Failure is at %d',failure))
or maybe you would rather put it on the plot directly:
annotation('textbox',[.7,.1,.1,.1],'String',sprintf('Failure is at %d',failure))

Try this
% Find first element where x exceeds 6
index = find(x>6, 1, 'first');
% Get the x and y values for that index
x6 = x(index);
y6 = y(index);
% Make up a message to put on the plot:
message = sprintf('Failed at (x,y) = (%f, %f)', x6, y6);
% Place the message in a text box near the x,y point:
text(x6, y6, message, 'FontSize', 14);
