代码说明:

  he form of the Burgers equation considered here is: du du d^2 u -- + u * -- = nu * ----- dt dx dx^2 for -1.0 < x < +1.0, and 0.0 < t. Initial conditions are u(x,0) = - sin(pi*x). Boundary conditions are u(-1,t) = u(+1,t) = 0. The viscosity parameter nu is taken to be 0.01 / pi, although this is not essential. The authors note an integral representation for the solution u(x,t), and present a better version of the formula that is amenable to approximation using Hermite quadrature. This program library does little more than evaluate the exact solution at a user-specified set of points, using the quadrature rule. Internally, the order of this quadrature rule is set to 8, but the user can easily modify this value if greater accuracy is desired.

  • GPS
    利用Matlab生成GPS C/A 码的基带信号。 (1)产生卫星PRN 号码为“5”的一组C/A 码; (2)循环生成25 页的导航数据,GPS 时间可填入一固定的已知数值; (3)生成C/A 码扩频信号,每个C/A 码码片给出4 个采样数据; (4)基带信号采用方波信号,电平为0 和1,占空比为50 %,不加入噪声,进一步生成某个特定的中频信号。(Matlab generated using GPS C/A code base band signal. (1) generation of satellite PRN number is " 5" a set of C/A code (2) loop generates 25 of the navigation data, GPS time can fill a fixed known value (3) to generate C/A code spread spectrum signal, each C/A code chip gives the four sampling data (4) baseband signals using square wave signal, level 0 and 1, 50 duty cycle, not to join the noise generated further a specific frequency signal.)
