您无法使用csvread读取文本字符串。 这是另一个解决方案:fid1 = fopen('test.csv','r'); %# open csv file for reading fid2 = fopen('new.csv','w'); %# open new csv file while ~feof(fid1) line = fgets(fid1); %# read line by line A = sscanf(line,'%*[^,],%f,%f'...

代码是一行一行向下逐步运行的,脚本上有很多代码,当我们想要代码跳过某些行的运行直接运行下面的代码时,我们可以采用Matlab中的判断语句。 The code is run down line by line step by step. There is a lot of code on the script. When we want the code to skip the running of some lines and directly ...
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。 start="I"+newline;fin="II";sonnet1...
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,...
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); % 从文件读行 nline=nline+1; if nline==line fprintf(fidout,'%s\n',tline); ...
Then, I use the csvread command to extract the numerical part of the file. But there should be a (much) easier way to do it! First, I don't want to read the whole file (as with a = textscan(fid,'%s','Delimiter','\n');) to extract only the first line. Second, it looks ...
textscan 从文本文件中读入数据,将结果保存为单元数组 下面详细介绍这些函数。 1. csvread、csvwrite csvread函数的调用格式如下: ● M = csvread('filename'),将文件filename中的数据读入,并且保存为M,filename中只能包含数字,并且数字之间以逗号分隔。M是一个数组,行数与filename的行数相同,列数为filename列...
