% [FID, MESSAGE] = FOPEN(FILENAME,...) returns a system dependent error message if % the open is not successful. % % [FID, MESSAGE] = FOPEN(FILENAME,PERMISSION,MACHINEFORMAT) opens thespecified% file with the specified PERMISSION and treats data read using FREAD or data % written using...
COUNT=FPRINTF(FID,FORMAT,A,...) 将矩阵A实部格式化，在指定FORMAT字符串控制下，写入FID文件ID指定文件中，COUNT是成功写入的字节数。FID由FOPEN获得的整数文件ID，也可设为1：标准输出（屏幕）（缺省的是此情况）；2：标准错误
fid is a scalar MATLAB integer, called a file identifier. You use the fid as the first argument to other file input/output routines. If fopen cannot open the file, it returns -1. Two file identifiers are automatically available and need not be opened. They are fid=1 (standard...
调用方法为：tline = fgetl(fid);其中，fid是已经打开的文件句柄，可以按照如下方法打开：fid=fopen('目标文件名');fgetl返回和fid相关联的文件的下一行，若到达文件末尾，则返回-1，通常用于处理纯文本文件。tline不包括行末尾的终结符，要想得到该换行符，使用fgets。 returns the next line of the...
Matlab code opens a file; fopen returns -1 on error. Pythonic code would raise exception, but we are not going to do that. Instead, we will live with the accent, and smop takes this to the extreme --- the matlab program remains mostly unchanged. It turns out that generating matlabic`...

~feof 是在 feof 前加了“非”，是逻辑表达式：文件指针到达文件末尾时 该表达式值为“假”；否则为“真”；while ~feof 表示 若 未读到文件末尾 则 继续 循环 while feof 表示 若 未读到文件末尾 则 终止 循环，所以只循环一次就终止了，运行结果自然为0 这些都是程序设计的基本知识，你仔细想...
Fopen function FOPEN open file. 打开文件。 FID = fopen(Filename) opens the file Filename for read access. (On PC systems, fopen opens files for binary read access.) FID is a scalar MATLAB integer, called a file identifier. If FOPEN cannot open the file, it returns -1. FID= fopen(...
