%将数据存储在csvdata中,并保存为cell形式 五、matlab批量导入csv文件(也可以将循环中的csv文件替换成其他类型的文件) 1 2 3 4 5 6 7 8 9 10 11 12 13 %导入数据方式参考:https://blog.csdn.net/zzx2016zzx/article/details/86696313 clc,clear; s=what; p=s.path; %当前文件夹路径 filename=dir(...
newData1 = importdata('DOW.txt');或者 path='DOW.txt'newData1 = importdata(path);不过importdata不支持后缀名为txt文件，其支持的文件后缀有：Data formats Command Returns MAT - MATLAB workspace load Variables in file.CSV - Comma separated numbers csvread Double array...
● M = csvread('filename', row, col),读取文件filename中的数据,起始行为row,起始列为col,需要注意的是,此时的行列从0开始。 ● 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...

Load the file data.csv and preview its contents in a text editor. A screen shot is shown below. Notice the file contains data separated by commas and also contains empty values. Read the file, converting empty cells to -Inf. Get filename = 'data.csv'; fileID = fopen(filename); C...
LOAD/SAVE 主要的high level file I/O routines 是LOAD和SAVE函数。LOAD 可以读MAT-file data或者用空格间隔的格式相似的ASCII data. SAVE可以将MATLAB变量写入MAT-file格式或者空格间隔的ASCII data。大多数情况下,语法相当简单。下面的例子用到数值由空格间隔的ASCII filesample_file.txt: ...
读写csv文件可以使用基础python实现，或者使用csv模块、pandas模块实现。 基础python读写csv文件 读写单个...
Here is a sample of how you should be able to load and create a 2D plot. data = csvread('mydatafile.csv',4);% Read the data plot(data(:,1),data(:,2))% Plot x vs time If there are other things you are stuck with, please expand with more specifics. ...
A = exist('FileName') exist('mydata04.xlsx') % 文件存在,返回 2 exist('mydata05.csv') % 文件不存在,返回 0说明:exist 函数不仅可以用来检验文件是否存在, 还可以检验指定的文件夹、工作区中的变量、以及 MATLAB 的系统函数等内容 是否存在.如果它们不存在,exist 返回 0,否则返回非 0,详细信息请查阅...
