在使用matlab将数据导入到工作空间的时候,经常会使用到两个函数,一个是importdata函数,另一个是load函数,它们的使用方法和使用场景是太相同的,如果不太注意就可能会犯错误,在这里做简要的说明和记录。 2.importdata函数 下面是帮助文档提供的importdata函数的语法说明 importdata load data from
Data Types:single|double|int8|int16|int32|int64|uint8|uint16|uint32|uint64 Output Arguments collapse all Data from the file, returned as a matrix, multidimensional array, or scalar structure array, depending on the characteristics of the file. Based on the file format of the input file,impo...
A = importdata(filename) loads data into array A. A = importdata(‘-pastespecial’) loads data from the system - clipboard rather than from a file. A = importdata(_,delimiterIn) interprets delimiterIn as the column separator in ASCII file, filename, or the clipboard data. Youcanuse deli...
Read Different Types of Data Copy Code Copy Command Load the data file and read each column with the appropriate type. Load file scan1.dat and preview its contents in a text editor. A screen shot is shown below. Get filename = 'scan1.dat'; Open the file, and read each column with...
The Import Tool lets you interactively select and import MAT, text, spreadsheet, media (image, audio, and video), and scientific data (HDF5 and netCDF) files.
I am not able to load data from a file which was saved as a text-file from MS Excel. textscan and load return an empty matrix. I tried to retype the data within the file using MS Notebook, to save the file with new name, however without success. If I ...
importdata load data from file Syntax A = importdata(filename) A = importdata(‘-pastespecial’) A = importdata(_,delimiterIn) A = importdata(_,delimiterIn,headerlinesIn) [A,delimiterOut,headerlinesOut] = importdata(_) Description - A = importdata(filename) loads data into array A. - A ...
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: ...
1. 逐一以文本形式打开文件 file(n).txt ; 2. 逐行读出数据,并判断前9个字符是否 Timestamp ; 3. 如是,在下一行接收数据存入结果并退出此文件; 4. 如不是,继续往下读数据。pt = 'd:\data\'; % 数据路径 ff = 'file'; % 数据文件前缀 ext = '.txt'; % 数据文件扩展名 s ...
