Welcome to Beginning Algorithms, a step-by-step introduction to computing algorithms for the real world.
Developers use algorithms and data structures every day of their working lives. Having a good understanding
of these algorithms and knowledge of when to apply them is essential to producing software
that not only works correctly, but also performs efficiently.
This book aims to explain those algorithms and data structures most commonly encountered in day-today
software development, while remaining at all times practical, concise, and to the point, with little or
no verbiage to distract from the core concepts and examples.

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. while Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

This demo shows the use of the PWM block in generating the pulse waveform whose duty cycle is changing regularly. The PWM waveform period is variable, while the width of the pulse remains constant.

詞法分析是編制一個讀單詞的過程，從輸入的源程序中，識別出各個具有獨立意義的單詞，即基本保留字、標(biāo)識符、常數(shù)、運算符、分隔符五大類。并依次輸出各個單詞的內(nèi)部編碼及單詞符號自身值。程序語言的單詞符號一般分為五種：關(guān)鍵字（保留字/基本字）if、while、begin…；標(biāo)識符：常量名、變量名…；常數(shù)：34、56.78、true、‘a(chǎn)’、…；運算符：+、-、*、/、〈、and、or、….、；界限符：， ； （ ） { } /*…。

構(gòu)造一個簡單程序設(shè)計語言的詞法分析器，要求：
1） 含有保留字program, begin, end, var, integer, if, then, else, do, while.
2） 標(biāo)識符和無符號的整常數(shù)，其中保留字和標(biāo)識符不區(qū)分大小寫.
3） 含有界符和運算符如下：+,-, (, ), =, >, <, , :, :=.,,。
4） 輸出二元組。
