In order to achieve small size, light weight, and immunity to electromagnetic interference, it is desirable to replace bulky coaxial cables with optical fiber in advanced radar front-ends. Such applications require a large dynamic range that is beyon
弃用-Javascr ipt 1

In this module you'll make a start into wonderful world of programming. We will be using the programming language `Javascr ipt` to do so. You'll learn about the basic building blocks of programming: `loops`
The Ape Programming Language
About
Ape is an easy to use programming language and library written in C. It's an offspring of language (from and books by ), but it evolved to be more procedural with variables, loops, operator overloading, modules,
We present a study of the effect of imperfections on the transmission and crosstalk in programmable photonic meshes with feedback loops consisting of tunable couplers and phase shifters. The many elements in such a mesh can generate a multitude of pa
下面是python中的一个函数计算代码：
loops=25000000
from math import*
a=range(1,loops)
def f(x):
return 3*cos(x)+4*sin(x)**2
%timeit r=(f(x) for x in a)
效率：
1000000 loops, best of 3: 552 ns per loop
下面我们就来看一下提高计算速度的方法：
1、使用数组
import numpy as np
a = np.arange(1
//linux下ALSA播放声音的源程序
//note 编译的时候，使用到了asound 的lib 所以要添加-lasoud库
#include
/* Use the newer ALSA API */
#define ALSA_PCM_NEW_HW_PARAMS_API
#include
int main()
{
long loops;
int rc;
int size;
snd_pcm_t *handle;
snd_pcm_hw_params_t *params;
