Open in MATLAB Online I am trying to implement numerical partial differentiation in MATALB wihtout using the built-in functions. I have a function vel = x+exp(-((x-x(1)).^2+(y-y(1)).^2)) of two variables with x ranging from -1 to 1 and y range from -2 to 2, with in...
Geometry and graphics were important parts of the Calculus Reform movement and can be used to advantage in the teaching of concepts of differentiation and integration as reflected in modern calculus texts Differential equation pedagogy can be enhanced by use of integral curve and direction field ...
MATLAB Online에서 열기 Ran in: After all of those comments, to be honest, sorry, but you were both working far too hard on a moderately simple problem. Simplest is to just create a polygon, then use polyarea of that object. Alternatively, create a polyshape object. Again, compute...

The central idea of stabilized explicit Runge–Kutta methods is to use additional stages primarily to improve the stability properties of the scheme, i.e., allow for larger timesteps. In particular, one usually settles for a moderate order of accuracy and uses the additional degrees of freedom ...
