What i am having trouble finding is how to get a title of a graph to display the sign for both positive and negative input. What i have done so far is this.
%Determine what the quadratic is.
disp('What are the quadratics coefficients?');
a = input('Coefficient A=');
b = input('Coefficient B=');
c = input('Variable C=');
disp('Thank you, calculating now.');
%display graph and customize it
plot(x,y, '--b', 'LineWidth', 3)
grid on
xlabel ('x')
ylabel ('f(x)')
title (['f(x)=' num2str(+a) 'x^2' num2str(+b) 'x' num2str(+c)])
The title is the quadratic function but like this only shows the "-" but i need it to show the "+" if it is a positive number.
Any pointers?
