It is shows how to display and model scalar and vector fields using EJS.
Edit By BS Editor: The Scalar Field Gradient Model displays the gradient of a scalar field using a numerical approximation to the partial derivatives. This simple teaching model also shows how to display and model scalar and vector fields using EJS.

The EJS Scalar Field Gradient Model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_math_ScalarFieldGradient.jar file will run the program if Java is installed. you can free download Scalar Field Gradient Model now.
