Solve Equations with One Initial Condition To solve the Lotka-Volterra equations in MATLAB®, write a function that encodes the equations, specify a time interval for the integration, and specify the initial
so I've been having a hard time figuring out all the parameters that bvp4c and bvp5c require but which ode45 does not - specifically the boundary condition function, thebvpinitparameter,
Solve the ODE y′=−10t. Specify a time interval of [0 2] and the initial condition y0 = 1. Get tspan = [0 2]; y0 = 1; [t,y] = ode23t(@(t,y) -10*t, tspan, y0); Plot the solution. Get plot(t,y,'-o') Solve Stiff ODE Copy Code Copy Command An example of ...
Solve this nonlinear differential equation with an initial condition. The equation has multiple solutions.(dydt+y)2=1y(0)=0Get syms y(t) ode = (diff(y,t)+y)^2 == 1; cond = y(0) == 0; ySol(t) = dsolve(ode,cond)
