打开或创建一个CSV文件: 使用fopen函数可以打开或创建一个CSV文件,并获取文件标识符(fid)。 matlab fid = fopen('output.csv', 'w'); 使用MATLAB的写入函数将数据写入CSV文件: 有几种方法可以将数据写入CSV文件,包括csvwrite、writematrix、writetable和fprintf等。 使用csvwrite函数(适用于矩阵数据): matlab csv...
1：将csv⽂件在MATLAB中导⼊为向量 要⽤到MATLAB中的csvread（）函数，官⽅⽂档如下：M = csvread(filename)M = csvread(filename,R1,C1)M = csvread(filename,R1,C1,[R1 C1 R2 C2])Description （1）M = csvread(filename) reads a comma-separated value (CSV) formatted file into array...
● M = csvread('filename', row, col, range),读取文件filename 中的数据,起始行为 row,起始列为col,读取的数据由数组 range 指定,range 的格式为:[R1 C1 R2 C2],其中R1、C1为读取区域左上角的行和列,R2、C2为读取区域右下角的行和列。 csvwrite 函数的调用格式如下: ● csvwrite('filename',M)...

将MATLAB计算出的数据进行导出和存储,是编程中常用的功能。MATLAB提供如writetable、xlswrite、writematrix、writecell等方法,其中writetable功能全面,本文选择使用writetable实现数据写入文件。常规做法中,我们通常会将数据写入csv文件。例如,有如下表格数据,将其写入csv文件的代码如下:然而,为了简化代码,本 ...
● csvwrite写入数据时每一行以换行符结束。另外,该函数不返回任何值。 2、excel数据导入指令 data = xlsread('a.xls'); 首先要把a.xls文件放到matlab工作目录下 3、对于纯文本型的 TXT 文件 可以直接用x=load('a.txt') 补充: MATLAB中有两种文件I/O程序:high level and low level. ...
csvwritedoes not accept cell arrays for the input matrixM. To export a cell array that contains only numeric data, usecell2matto convert the cell array to a numeric matrix before callingcsvwrite. Algorithms csvwriteterminates each line with a line feed character ('\n'orchar(10)) and no ca...
Now my question is: How can i write this back into a csv file? I've tried with fprintf, cell2csv (online) and numerously other online scripts but I haven't found anything to help me do this. Thanks in advance for your help and time. ...
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 ...
