streamline()

Plotting

streamline() is a MATLAB®-compatible plotting function for streamline plot. traces flow lines through a 2d vector field using rk4 integration. x, y define the grid, u, v are velocity components, and startx, starty are seed points.

What does streamline() do?

Streamline plot. Traces flow lines through a 2D vector field using RK4 integration. X, Y define the grid, U, V are velocity components, and startX, startY are seed points. It is a MATLAB®-compatible plotting function available in SimLab with the same calling syntax as MATLAB® — typically: streamline(X, Y, U, V, startX, startY).

Can I run streamline() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls streamline(), and run it. Execution happens locally in your browser — no data leaves your machine.
