I have made a program that calculates the root of a function. I want to have text saying "the root of the function is at x=(result calculated by program) on the plot. I am using the text command to print the message where I want but I don't know how to print the result itself on plot. Can someone help me?

use num2str to convert the result to string and use it inside text command,
text(x_pos, y_pos, ['the root of the function is at x = ', num2str(result)])
