I used this code but i think is in not working right.

>> clc;

clear all;

tspan = [-1 2];

y0 =- 3;

%ode45

[x,y] = ode45(@(x,y) y^2-x^2, tspan, y0);

plot(x,y,'r')

hold on

y01=0;

[x,y1] = ode45(@(x,y) y^2-x^2, tspan, y01);

plot(x,y1,'b')

xlabel('x','fontsize',15)

ylabel('y','fontsize',15)

legend('y(-1)=-3','y(-1)=0')

title('my namei','fontsize',25)

text(0,0.01, datestr(clock), ...

'Units', 'normalized', ... % Not depending on the data

'HorizontalAlignment', 'left', ...

'VerticalAlignment', 'bottom');

Consider the following differential equation: dy a. Use the MATLAB routine ode45 to generate approximate solutions to this differential equation over the interval-l
