Simulacion de sistema de potencia mediante simulink y Archivo M
Saludos! necesito desarrollar la simulacion de un sistema de potencia donde el sistema se diseña en simulink y los valores de impedancia son leidos mediante un archivo M el cual genera un reporte mostrando la matriz de admitancia de nodo y la matriz de impedancia de barra y los calculos de la corriente corto circuito. ... 11 Jun 2010 13:40

Chemotaxis PDE Solution with pdepe
I am trying to solve a system of PDEs that includes diffusion and chemotaxis terms. The equations are: dn/dt = d^2n/dx^2 - d/dx(n*dc/dx) dc/dt = d^2c/dx^2 so the first equation includes a second derivative of c. I can't figure out a way to program this using pdepe, because the format of the pdex1pde function onl... 16 Jun 2010 12:08

rotate a matrix with dimension m,n,p. (image the density of a 3D box)
Dear ALL I have a 3-D space, there are m, n, p points along x, y, z respectively. at each (x,y,z), there is an density, I(x,y,z). Physically, it is like a density map inside a 3-D box. and the density are stored in a matrix, m by n by p. I'd like to rotate this matrix using euler angles. The euler rotation matri... 15 Jun 2010 01:06
