How to add calculated parameters in to plot title

Hi,

I have below example plot, and I want to add more calculated parameters, but it give error.

x_variable=1:1:10;
y_variable=0.1:0.1:1;
mean_ab=mean(x_variable);
max_ab=max(x_variable);
std_ab=std(x_variable);

plot(x_variable,y_variable,'b--o')

title('x_variable:', mean_ab, max_ab, std_ab)

error is below:

Index exceeds matrix dimensions.

Error in titleplot (line 15)

title('x_variable:', mean_ab, max_ab, std_ab)

Try this:

title(sprintf('x\\_variable: \\mu = %.2f, max = %.2f, \\sigma = %.2f', mean_ab, max_ab, std_ab))

Experiment to get the result you want.

If I want to print variable name, max, mean in one line and std_ab in another line

title(sprintf('x\\_variable: \\mu = %.2f, max = %.2f, \\sigma = %.2f', mean_ab, max_ab, std_ab))

I do this like but it only print second line.

title(sprintf('x\\_variable: \\mu = %.2f', max = %.2f, mean_ab, max_ab))

title(sprintf(\\sigma = %.2f', std_ab))

No need for two title calls (that likely would not do what you want anyway). Just insert a carriage return-linefeed (\n):

title(sprintf('x\\_variable: \\mu = %.2f, max = %.2f\n\\sigma = %.2f', mean_ab, max_ab, std_ab))

That should do what you want (and is another advantage of using sprintf here).

As always, my pleasure.
