展频PLL时钟（SSC）产生电路，可以产生三角波、正弦波或者单频载波(Delta_Sigma Modulator, to be used in TXPLL with SSC modulation. this program simulates the Spread spetrum clocking scheme. the SSC can be set to triangle wave or sinewave, or you can also set it to be constant frequency which without SSC. the relevant parameters is programmable. )

加权最小二乘迭代求解多参数估值。用于求解平差问题及其他领域优化问题。(The weighted least-squares iterative solution of multi-parameter estimates. Adjustment for solving optimization problems and other problem areas.)

通过使用平面波发计算光子晶体能带图，这个图是我自己弄的，非常辛苦。但是希望能给从事光学研究的朋友的带来帮助。(Calculating the bandgap of a photonic crystal by using a plane wave gives me a very hard picture of myself. But I hope to help those who engage in optical research.)

this is basic matlab explanation. i will upload 5documents.
