Abstract:
To solve the problem of DC-AC inverter， and to utilize solar energy more efficiently， the design of maximum power point tracking inverter based on IR2101 was achieved with a high-performance， which can make the system output power maximum. SPMC75F2413A was adopted as main controller. IR2101 is a high voltage， high speed power MOSFET and IGBT driver. It adopted highly integrated voltage level transforming technology， and an external bootstrap capacitor was used， which could drive MOS tube efficiently and stably. Many functions are achieved in the system， such as DC/AC conversion， maximun power point tracking， etc. The actual test result shows that the inverter system has characteristics of strong tracking ability， high stability and reacting quickly. The design can not only be used in Ordinary power inverter system， but also be used in photovoltaic power inverter system. The design has certain marketing prospects
YSS915 (KP2V2) is an LSI for processing Karaoke voice signals.
This LSI has an A/D converter (1 channel) for the microphone echo, and a memory for the microphone echo and
key control. These features allow achieving the functions needed for the Karaoke system by using only one LSI
chip. As for the microphone echoes, many other types of echoes are available in addition to Ordinary ones so that
YSS915 is applicable to various uses.
In addition to these Karaoke programs, YSS915 is able to provide the Movie & Music programs, with which the
surround effect is applied to the movie and music sources for giving the users more enjoyment.
YSS915 is pin compatible with and register compatible with YSS903 (KP2V).
ICP fit points in data to the points in model. Fit with respect to minimize the sum of square errors with the closest model points and data points.
Ordinary usage:
[R, T] = icp(model,data)
INPUT:
model - matrix with model points,
data - matrix with data points,
OUTPUT:
R - rotation matrix and
T - translation vector accordingly
so
newdata = R*data + T .
newdata are transformed data points to fit model

Numerical Computing with MATLAB （by Cleve Moler) is a textbook for an introductory course
in numerical methods, Matlab, and technical computing. The emphasis is on in-
formed use of mathematical software. We want you learn enough about the mathe-
matical functions in Matlab that you will be able to use them correctly, appreciate
their limitations, and modify them when necessary to suit your own needs. The
topics include
* introduction to Matlab,
* linear equations,
* interpolation,
* zero and roots,
* least squares,
* quadrature,
* Ordinary di?erential equations,
* random numbers,
* Fourier analysis,
* eigenvalues and singular values,
* partial di?erential equations.
