数学问题：实用下料中下料方式，余料，matlab编程(Mathematical problems: A practical way of cutting material, more than expected, matlab programming)

This is a m.file that buid the map from sensor (like laser). Previous you will need info from some mdl.file s simulink. Basically: First Run the mdl.file and after rund de m file.

非平稳信号经过分解后，对其进行谱分析，此希尔伯特谱程序，弥补了了以前的缺陷(Non stationary signal through decomposition, the spectral analysis, the Hilbert spectrum procedures, make up for the previous defect)

基于MATLAB的OFDM仿真程序，仿真模块包括BPSK,QPSK,16QAM,64QAM(MATLAB simulation program based on the OFDM simulation module including BPSK, QPSK, 16QAM, 64QAM)

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.
