Adding text on the graph

Hello

I am making multiple plots of two matrixes and I am calculatting correlation coefficient i each case between these matrixes

I want to add correlation coefficient on the graph but I do not want to do it manyally in case of each graph

is there any possible way to generally convert this correlation coefficient value into string and then put this string as a text on the graph

can anyone provide me with proper code to do that

Thank you in advance

Look at text command and num2str

text(x,y,num2str(correlationCoefficient))

Not sure what you mean by manually but you can put in code to put text somewhere on your graph.

plot(1:10);
grid on;
xl = xlim;
yl = ylim;
r = 0.995;
xCenter = mean(xl);
yCenter = mean(yl);
str = sprintf('The correlation coeff = %f', r);
text(xCenter, yCenter, str, 'HorizontalAlignment', 'center', 'Color', 'r', 'FontSize', 14);
