compression

Speech compression using Linear Predictive Coding. LPC is the oldest and the most basic of modern speech coders. Its a lossy scheme. Playback quality isn t preserved in the process but it can be used in low bit-rate systems.

比例积分型的GPC，由新的目标函数解出的控制率与常规PI控制有着一样的形式，这样就获得了一种具有PI结构的广义预测控制，而且其参数 、 有着明显的工程意义，整定原则基本类似于PID。(Proportional-integral-type GPC, the new objective function solution of the control rate with conventional PI control has the same form, so to obtain a PI structure with generalized predictive control, and its parameters, there is a clear sense of the project, setting basic principle is similar to PID.)

This program shows how convolution works, going through all the steps of exactly what gets added up and multiplied with what. It also explains from the ground-up how to do for-loops in Matlab. (By the way, if you want to see an example of how to "vectorise" code to avoid for-loops altogether, look at the bkprop.m program in my
