In Matlab, a) Plot a vector field of the system y(x + y - 1) dx dt dy dt in a window [-2 2-2 2] b) Plot the graphs of the solutions of the above system with initial conditions = -x(x + y - 1) x(0) .25, y(0) =. 25; x(0) = 1.1, y(0) = 1.1; x(0) =.5, y(0) =.5 x(0) = 1.2, y(0) = 1.2 In Matlab, a) Plot a vector field of the system y(x + y - 1) dx dt dy dt in a window [-2 2-2 2] b) Plot the graphs of the solutions of the above system with initial conditions = -x(x + y - 1) x(0) .25, y(0) =. 25; x(0) = 1.1, y(0) = 1.1; x(0) =.5, y(0) =.5 x(0) = 1.2, y(0) = 1.2
