You can read in the file line by line using the lower-level functions, then parse each line manually. You open the file handle like in C fid = fopen(filename); Then you can read a line usingfgetl line = fgetl(fid); String tokenize it on spaces is probably the best ...
CSVREAD用来读分隔符是逗号的文件,是DLMREAD的特殊情况。当读空格和Tab分隔的电子数据表文件时,DLMREAD特别有用。以'sample_file.txt'为例: [Copy to clipboard][ - ] CODE: Example 1: Using DLMREAD to read in a file with headers, text, and numeric data % This reads in the file 'sample_file2....
下面这个函数是取filein中的第line行写入fileout中的程序,如果想实现取特定几行,只要稍微修改一下就可以。 function dataout=dataread(filein,fileout,line) fidin=fopen(filein,'r'); fidout=fopen(fileout,'w'); nline=0; while ~feof(fidin) % 判断是否为文件末尾 tline=fgetl(fidin); % 从文件...
Example 1: Using TEXTREAD to read in an entire file into a cell array % This command reads in the file fft.m into the cell array, file file = textread('fft.m','%s','delimiter','\n','whitespace',''); CODE: Example 2: Using STRREAD to read the words in a line % This command...
17、eates a file called partialD.txt that consists of% the first 3 columns of the last 3 rows of data where each% element is separated by a commadlmwrite(partialD.txt,D_partial,)注意: 保证DLMREAD and DLMWRITE指定范围的指标从0开始,而不是从1开始。WK1READ/WK1WRITEWK1READ用来读Lotus123 电子...

Example:Using IMPORTDATA to read in a file with headers, text, and numeric data % This reads in the file 'sample_file2.txt' and creates a % structure D that contains both data and text data. % Note the IMPORTDATA command specifies a white...
I would try to read the entire file in one while loop, line by line, until the end of the file is reached: % Open files fid = fopen('test.txt'); % Read Data i = 1; j = 1; while(~feof(fid)) line = fgetl(fid); if strfind(line,'.') i = i + 1; continue; end; s ...
要从PDF 表单中读取数据,请使用readPDFFormData。 文本文件 用extractFileText,从sonnets.txt中提取文本。文件sonnets.txt包含纯文本形式的莎士比亚十四行诗。 filename="sonnets.txt";str=extractFileText(filename); 通过提取两个标题I和II之间的文本,来查看第一首十四行诗。
方法/步骤 1 出现这一报错,一般是因为Excel的COM加载项增多了。我们在安装Foxit Reader、EViews等软件时,在默认情况下,会增加Excel的COM加载项。所以,当MATLAB报错:错误使用xlsread(line249)时,我们需要检查Excel的COM加载项,去掉新增加载项前面的勾选符号。首先,打开工作簿1.xlsx,在菜单栏中,找到文件,...
