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.

quadgui
该代码展示了如何通过数值方法估计某个量值的思路，方法具有新颖之处。。。望采纳(QUADGUI Demonstrate numerical evaluation of a definite integral.
Q = QUADGUI(F,A,B) shows the steps in approximating the integral
of F(x) from A to B by adaptive extrapolated Simpson s quadrature.
The shaded area shows the integral over the current subinterval.
The color switches to green when the desired accuracy is obtained.)

OFDMcode
OFDM信号的编码译码仿真，英文说明更详细。(This simulation script set allows for an OFDM transmission to be
simulated. Imagetx.m generates the OFDM signal, saving it as a
windows WAV file. This allows the OFDM signal to be played out a sound
card and recorded back. Imagerx.m decodes the WAV to extract the
data.
settings.m contains all the common settings to specify all the
simulation parameters such as FFT size, number of carriers,
input data source file, input and output WAV files, etc.
See settings.m for more details.
Note: The both the receiver and transmitter must have a copy of the
input data file, as this is used for calculating the exact number
of data words in the transmission.
The scripts should work as extracted. Just run imagetx.m to generate the
OFDM signal. Then run imagerx.m to decode the signal. The initial settings
transmit a wave file Corrs.wav . The decoded OFDM data ( Out.wav ) can be
compared with the original data by listening to the two wave files.)
