Offset quadrature phase-shift keying (OQPSK) is a variant of phase-shift keying modulation using 4 different values of the phase to transmit. It is sometimes called Staggered quadrature phase-shift keying (SQPSK).

this mfile is riten in matlab and is related to mirtoolbox

用matlab编制的机器人求逆以及求时间的程序，个人感觉很有应用借鉴价值。(using Matlab based robot inverse time and the procedures for seeking personal feeling good application reference value.)

In numerical analysis, Newton s method (also known as the Newton–Raphson method), named after Isaac Newton and Joseph Raphson, is a method for finding successively better approximations to the roots (or zeroes) of a real-valued function. The algorithm is first in the class of Householder s methods, succeeded by Halley s method. The method can also be extended to complex functions and to systems of equations.
