Fantastically a good book on C++

例4：在sinc(t)信号中叠加噪声，分析对应频谱 fs=100 采样频率,必须大于两倍基带信号最高频率 ts=1/fs 采样时间间隔 T=2 时间窗大小 ( x=x+0.1*randn(1,N) x=awgn(x,-10, measured ) figure plot(t,x) title( 时域信号图 ) xlabel( t /s ) y=fft(x,N) figure if mod(N,2)~=0 N=N-1 end f=linspace(0,fs/2,N/2) plot(f,abs(y(1:N/2))*2/N) title( 叠加噪声的sinc(t)信号频谱 ) xlabel( f /Hz ) figure y0=y(1:N/2) P=y0.*conj(y0)/N P=10*log10(P) plot(f,P) title( 功率谱 ) xlabel( f /Hz ) )

说明：  rsa示例，实现了加密和解密的基本功能，供大家参考(rsa example, to achieve the basic functions of encryption and decryption, for your reference)

说明：  VB与MATLAB接口使用实例.保准一学就会。(VB and MATLAB interface examples.保准One school will be.)

lab 1 matlab ...on wireless sensor networks a very good, very good ah!...////

Link list memory application

ti关于rf天线的设计、调试方法，13.56M精讲( ti on rf antenna design, debugging method, 13.56M succinctly)

purebasic的入门书籍，虽然用purebasic的人很少，甚至分类都没他。不过这个语言还是不错的。(purebasic entry books, although very few people with purebasic, or even no his classification. However, the language is good.)

基于window 环境下的电话本程序 (Window environment based on phone book program)

用牛顿迭代法求方程 f(x)=x³ -x² -1=0 在x。=1.5附近的一个实根。取§=0.000001，取最大迭代数为60. (With Newton iteration equation for f (x) = x ³-x ² -1 = 0 in x. = 1.5 near the root of a real. Take § = 0.000001, take the largest number of 60 iterations.)
