matlab文件操作及读txt文件(fopen,fseek,fread,fclose) matlab文件操作 文件操作是一种重要的输入输出方式，即从数据文件读取数据或将结果写入数据文件。MATLAB提供了一系列低层输入输出函数，专门用于文件操作。 1、文件的打开与关闭 1）打开文件 在读写文件之前，必须先用fopen函数打开或创建文件，并指定对该文件进行的操作方式。fopen函数的调用格式为： fid=fopen（文件名，‘打开方式’） 说明：其中fid用于存储文件句柄值，如果返回的句柄值大于0，则说明文件打开成功。文件名用字符串形式，表示待打开的数据文件。常见的打开方式如下：λ‘r’：只读方式打开文件（默认的方式），该文件必须已存在。 ‘r+’：读写方式打开文件，打开后先读后写。该文件必须已存在。λ λ‘w’：打开后写入数据。该文件已存在则更新；不存在则创建。 ‘w+’：读写方式打开文件。先读后写。该文件已存在则更新；不存在则创建。λ λ‘a’：在打开的文件末端添加数据。文件不存在则创建。 λ‘a+’：打开文件后，先读入数据再添加数据。文件不存在则创建。 另外，在这些字符串后添加一个“t”，如‘rt’或‘wt+’，则将该文件以文本方式打开；如果添加的是“b”，则以二进制格式打开，这也是fopen函数默认的打开方式。
2）关闭文件 文件在进行完读、写等操作后，应及时关闭，以免数据丢失。关闭文件用fclose 函数，调用格式为： sta＝fclose(fid) 说明：该函数关闭fid所表示的文件。sta表示关闭文件操作的返回代码，若关闭成功，返回0，否则返回-1。如果要关闭所有已打开的文件用fclose(‘all’)。 2、二进制文件的读写操作 1）写二进制文件 fwrite函数按照指定的数据精度将矩阵中的元素写入到文件中。其调用格式为：COUNT＝fwrite（fid，A，precision） 说明：其中COUNT返回所写的数据元素个数（可缺省），fid为文件句柄，A用来存放写入文件的数据，precision代表数据精度，常用的数据精度有：char、uchar、int、long、float、double等。缺省数据精度为uchar，即无符号字符格式。 例6.8 将一个二进制矩阵存入磁盘文件中。 >> a=[1 2 3 4 5 6 7 8 9]; >> fid=fopen('d:\test.bin','wb') %以二进制数据写入方式打开文件 fid =3 %其值大于0，表示打开成功 >> fwrite(fid,a,'double') ans = 9 %表示写入了9个数据 >> fclose(fid)

Matlab 的各种数据读取、文件读写等操作汇总 MATLAB 提供了多种方式从磁盘读入文件或将数据输入到工作空间，即读取数据，又叫导入数据；将工作空间的变量存储到磁盘文件中称为存写数据，又叫导出数据。至于选择哪种机制，则根据下面两个因素决定：?用户所执行的 操作是导入数据还是导出数据；?数据的格式为文本格式、 二进制格式还是如HDF 之类的标准格式。将数据导入MATLAB 中最容易的方法就是使用导入数据模板(Import Wizard) ，使用该模板时不需要知道数据的格式，只需指定包含这些数据的文件，然后导入模板会自动处理文件内容。本章重点内容如下：? 文件的打开和关闭? 文本文件的读取?存写ASCII数据?二进制数据的读取? 二进制数据的存写? 使用I/O文件函数进行数据读写?MAT 文件的读写 2.1 文件的打开和关闭2.1.1 文件的打开无论是要读写ASCII 码文件还是二进制文件，都必须先用fopen 函数将其打开，在默认情况下，fopen 以二进制格式打开文件，它的使用语法如下：fopen ('filename', 'mode') 其中filename 表示要读写的文件名称，mode 则表示要对文件进行的处理方式，如下：rt :以只读方式(Reading)打开文件wt:以只写方式(Writing)打开文件at:以追加方式(Appending)打开文件，新内容将从原文件后面续写r+t:以同时读写方式打开文件w+t ：以同时读写创建文件，原文件内容被清除
a+t ：以同时读和追加(Reading and Appdending) 方式，原文件内容被保留，新内容将从原文件的后面开始At ：以读写方式打开或创建文件，适用于对磁带介质文件的操作Wt ：以写入方式打 开或创建文件，原文件内容被清除，适用于磁带介质文件的操作fopen 函数有两个返回值，一个是返回一个文件标志(file Identifier) ，它会作为参数被传入其他对文件进行读写操作的命令，通常是一个非负的整数，可用此标识来对此文件进行各种处理。如果返回的文件标识是-1，则代表fopen无法打开文件，其原因可能是文件不存在，或是用户无法打开此文件权限。另一个返回值就是message ，用于返回无法打开文件的原因。为了安全起见，最好在每次使用fopen 函数时，都测试其返回值是否为有效值。下面以脚本m 文件为例来声明文件的打开。例 2-1 %exam1.m[f,message]=fopen('fileexam1', 'r')if f==-1disp (message); % 显示错误信息end 若文件fileexam1 不存在，则显示如下信息。Cannot open file.existence?permissions?memory?... 例2-2 %exam2.m[f,message]=fopen('fileexam2', 'r');if f==-1disp (message); % 显示错误信息else disp(f);end 若文件fileexam2 存在，则返回f值。 2.1.2 文件的关闭一旦完成文件的读写，最好关闭文件，以便对其进行其他操作。这时就可以使用fclose 函数来关闭文件，其适用语法如下：fclose(f) 。其中 f 为打开文件的标志，若fclose 函数返回值为0 ，则表示成功关闭 f 标志的文件；若返回值为-1，
Java流 一、流的分类 ?按数据流动方向 –输入流：只能从中读取字节数据，而不能向其写出数据 –输出流：只能向其写入字节数据，而不能从中读取数据?按照流所处理的数据类型 –字节流：用于处理字节数据。 –字符流：用于处理Unicode字符数据。 ?按照流所处理的源 –节点流:从/向一个特定的IO设备读/写数据的流。（低级流）–处理流:对已存在的流进行连接和封装的流。（高级流）二、缓冲流 ?缓冲流要“套接”在相应的节点流之上，对读写的数据提供了缓冲的功能，提高了读写的效率，同时增加了一些新的方法。 ?J2SDK提供了四种缓存流： –BufferedReader –BufferedWriter –BufferedInputStream s –BufferedOutputStream
?缓冲输入流支持其父类的mark()和reset()方法： –mark()用于“标记”当前位置，就像加入了一个书签，可以使用reset()方法返回这个标记重新读取数据。?BufferedReader提供了readLine()方法用于读取一行字符串（以\r 或\n分隔）。 ?BufferedWriter提供了newLine()用于写入一个行分隔符。 ?对于输出的缓冲流，写出的数据会先在内存中缓存，使用flush()方法将会使内存中的数据立刻写出。 三、类层次 3.1、InputStream类层次
3.2、OutputStream类层次 3.3、Reader类层次
3.4、Writer类层次 四、常用的字符流与字节流的转化 说明： 1.字节流用于读写诸如图像数据之类的原始字节流。 2.字符流用于读写诸如文件数据之类的字符流。 3.低级流能和外设交流。 4.高级流能提高效率。 5.InputStreamReader 是字节流通向字符流的桥梁。 6.OutputStreamWriter 是字符流通向字节流的桥梁。
文本文件的读写 正确的文本文件读写过程 1.定义文件变量； 2.打开指定的文件； 3.向从文本文件中写入信息； 4.从文本文件中读取信息； 5.关闭文件 1、定义文件变量 定义文件变量格式：CStdioFile 文件变量； 例如，定义一个名称为f1的文件变量，语句如下：CStdioFile f1; 2、打开指定文件 可以直接通过CStdioFile的构造函数来打开磁盘文件，同时可以用标志位指定打开方式（只读、只写、读写等）： CStdioFile(LPCTSTR lpszFileName,UINT nOpenFlags); 其中，lpszFileName表示要打开的文件名，可以是相对路径或绝对路径 nOpenFlags设置文件打开方式标志位，可以指定用“|”连接多个标志位。下面是常用的打开标志： CFile::typeText：以文本文件的形式打开文件 CFile::typeBinary：以二进制文件的形式打开文件 CFile::modeCreate：如果指定文件名的文件不存在，则新建文件；如果文件存在并且没有设置CFile::modeNoTruncate标志，则清空文件。 CFile::modeNoTruncate：如果文件存在，不把它的长度删除为0（即不清空文件中的数据）。
：以只读方式打开文件 CFile::modeReadWrite：以可读可写方式打开文件 CFile::modeWrite：以只写方式打开文件 CFile::shareDenyNone：文件打开后，不禁止其他进程对文件的读写操作CFile::shareExclusive：文件打开后，禁止其他进程对文件的读写操作CFile::shareDenyRead：文件打开后，禁止其他进程对文件的读操作
