MATLAB如何读取excel文件中的数据

Matlab提取Excel文件中部分内容

Matlab提取Excel文件中部分内容Excel表格整表操作十分方便，xlsread函数支持对表单的操作，也支持对某个矩形区域的操作。

比如要求把一表格的'A4:A6','C2:C4','E3:E5'的内容连续保存在新表格中。

连续保存没什么，重点是将不连续的区域读出来，虽然多次读取可以实现，但是如果读取海量表格中的几百列，几千这种方法就没有效率可言了，所以需要将表格的标号放到循环中去处理，让循环来代替手动读取，这样即使成千上万遍的读取也没有问题。

代码如下：复制内容到剪贴板代码:str={'A4:A6','C2:C4','E3:E5'};data=[];for ii=1:3A = xlsread('ff.xls', 1, str{ii});data=[data,A];enddata中保存的就是从不连续的区域读取来的内容。

上例中虽然读取方便，但是位置字符串设置仍不够方便，如果设置几百个或者几千个字符串位置，也够累的，所以可以将字符串中的数字也用循环变量来代替。

复制内容到剪贴板代码:str=['A','C'];data=[];for jj=1:2;for ii=1:3A = xlsread('ff.xls', 1, [str(jj),num2str(ii)])data=[data,A];endend上述就是读取A1:A3和C1:C3单元的内容。

filename1=ls('*xls');%取得所用excel文件filename=cellstr(filename1);num=length(filename);%得到excel文件的个数for ii=1:numM=xlsread(filename{ii});%执行对矩阵M的处理代码enddata=load('路径\文件.xls');data=xlsread('路径\文件.xls');可以通过Excel link 将Excel和MATLAB链接起来，就可以将Excel里面的数据以矩阵的形式导入MATLAB的工作区间workspace中，Excel link 的安装(1)启动Excel(2)单击工具加载宏命令，在弹出的加载宏对话窗口中单击浏览按钮。

matlab中各种数据的读取

matlab中各种数据的读取
在MATLAB中，可以使用不同的函数来读取各种类型的数据。

以下是一些常用的数据读取函数：
1. 读取文本文件：
- `textread`：读取格式化的文本文件。

- `fscanf`：按指定格式读取文本文件。

- `importdata`：读取文本文件，并将数据存储在结构体中。

2. 读取电子表格文件：
- `xlsread`：读取 Microsoft Excel 文件。

- `readtable`：读取 Excel、CSV 或者其他格式的表格文件，并将数据存储在表格对象中。

3. 读取图象文件：
- `imread`：读取图象文件，并将其存储为图象矩阵。

- `dicomread`：读取 DICOM 文件，并将其存储为图象矩阵。

4. 读取音频文件：
- `audioread`：读取音频文件，并将其存储为音频信号向量。

5. 读取视频文件：
- `VideoReader`：创建一个视频阅读器对象，用于逐帧读取视频文件。

6. 读取二进制文件：
- `fread`：按指定格式读取二进制文件，并将数据存储在矩阵中。

以上只是一些常用的数据读取函数，MATLAB还提供了许多其他函数，用于读取和处理各种类型的数据。

具体的使用方法可以参考MATLAB的文档或者在线匡助。

excel readtable函数的用法matlab

excel readtable函数的用法matlab在MATLAB中，没有直接与Excel的"READTABLE"函数相对应的函数。

但是，您可以使用"readmatrix"或"readarray"函数来读取Excel文件中的数据。

这些函数可以读取Excel文件中的单元格数据，并将其存储为矩阵或数组。

以下是使用"readmatrix"函数读取Excel文件的示例代码：```matlabfilename = 'example.xlsx';sheet = 1;range = 'A1:C10';data = readmatrix(filename, sheet, range);```在上面的代码中，您需要将"filename"替换为您要读取的Excel文件的文件名，"sheet"替换为要读取的工作表的索引或名称，"range"替换为要读取的单元格范围的地址。

读取的数据将被存储在名为"data"的矩阵中。

如果您需要读取的Excel文件中的数据是表格格式，则可以使用"readarray"函数。

以下是使用"readarray"函数读取Excel文件的示例代码：```matlabfilename = 'example.xlsx';sheet = 1;range = 'A1:C10';data = readarray(filename, sheet, range);```与"readmatrix"函数类似，您需要将"filename"、"sheet"和"range"替换为您要读取的Excel文件的文件名、要读取的工作表的索引或名称以及要读取的单元格范围的地址。

matlab读取excel数据

matlab读取exceloffice的表格文件也就是xls文件本质上就是一个二维矩阵，二维矩阵是用来保存数据的最佳方式，所以在日常工作中，我们从其它地方获取的数据通常都被保存为xls格式，但处理数据时，我们却需要把xls文件的数据导入到matlab里进行处理。

如果你只处理一个文件并且只做一次的话，你可以手动来拷贝粘贴，这花费不了你太多时间。

如果有很多xls文件，或者你的xls文件的内容可能随时被修改，那么下面的方法可以派上用场。

matlab自身提供了大量的函数，包括读取office文件。

其中xlsread和xlswrite就是专门用来读取xls文件里的数据的。

这两个函数的使用方法可以直接查看matlab自带的帮助。

xlsread对于纯数据的xls文件支持很完美，也就是说当xls文件里的每个格子都是“数”时，xlsread会直接返回一个实数矩阵。

但是通常我们拿到xls文件并不是这样，它的表头多半是描述性文字，它的数据也有可能是文字，有些位置的数据还有可能是缺失的。

xlsread 对这样的文件读取无能为力，或者说需要大量的时间去协调数据的位置信息。

要是有一个函数，能够按照原有的顺序直接读取所有的单位格数据就好了。

当然，这时候返回的矩阵就不能是一个数值矩阵了，它将会是一个cell矩阵，里面的每个元素类型可能不一样。

matlab本身并不提供这个功能，但是另外有一个函数officedoc完美的实现这个功能。

这个函数包可以去OfficeDoc官方网站上去下载，解压缩后放到工作路径上即可。

使用方法可以查询help officedoc。

officedoc是收费函数包，但有免费版本，而且其免费版本可以实现上面我们所说的效果（收费版本主要是可以用来修改office文件）。

例子：在matlab中读取xls格式的文件内容如应用如下函数:1.bb=xlsread('c:feature.xls','a0:an40'),其中:c:feature.xls为文件存放的地址,a0:a40为将要读取的单元格的范围.bb为读取的矩阵在MATLAB中的变量名.2.使用m文件脚本如下:Excel = actxserver('Excel.Application');set(Excel, 'Visible', 1);Workbooks = Excel.Workbooks;Workbook = invoke(Workbooks, 'Open', [cd,'\feature\ABC.xls']);%% 读取ABC.xls:sheet1 a1(即R1C1)~an40(即R240c40) 范围内的 40by40 矩阵read_excel=ddeinit('excel','ABC.xls:sheet1');feature1 = ddereq(read_excel, 'R1c1:R40c40');feature1%% 关闭ABC.xlsinvoke(Excel, 'Quit');delete(Excel);注意:在使用时将m文件与xls文件存于同一个目录下.另外:sheet1:可以重命名,且读取sheet的名称要和实际存放的名称相同.matlab读取excel,txt文件函数注意matlab不识别中文，读写的文件中最好不含有中文excel读取函数xlsreadtext 读取函数csvreadXLSREAD Get data and text from a spreadsheet in an Excel workbook.[NUMERIC,TXT,RAW]=XLSREAD(FILE) reads the data specified in the Excelfile, FILE.

matlab读取excel方法

matlab读取excel方法
在MATLAB中读取Excel文件，你可以使用readtable或readmatrix函数。

以下是使用这些函数的一些基本示例：1.
使用readtable读取Excel文件：
2.
matlab复制代码
% 读取Excel文件
T = readtable('你的文件
名.xlsx');
% 显示数据
disp(T);
readtable`函数将读取Excel文件并将其存储为一个表格（table）。

你可以使用各种MATLAB函数来查询、处理和分析这个表格。

3.
使用readmatrix读取Excel文件：
4.
matlab复制代码
% 读取Excel文件
M = readmatrix('你的文件
名.xlsx');
% 显示数据
disp(M);
readmatrix函数将读取Excel文件并将其存储为一个矩阵。

与readtable不同，readmatrix假设Excel文件中的所有数据都是数字，并将其转换为双精度浮点数。

如果你知道Excel文件中的数据类型，你可以使用readmatrix。

但是，如果你不确定数据类型，或者你的数据包含文本，那么你可能更喜欢使用readtable`。

注意：这些示例假设你的Excel文件是.xlsx格式的。

如果你的文件是.xls格式的，你可能需要使用不同的函数或方法来读取。

此外，为了读取Excel文件，你需要在MATLAB中安装Excel File Readers and Writers Toolbox。

For more information, refer to the individual comments for each code segment.% Open Excel, add workbook, change active worksheet,% get/put array, save, and close% First open an Excel ServerExcel = actxserver('Excel.Application');set(Excel, 'Visible', 1);% Insert a new workbookWorkbooks = Excel.Workbooks;Workbook = invoke(Workbooks, 'Add');% Make the second sheet activeSheets = Excel.ActiveWorkBook.Sheets;sheet2 = get(Sheets, 'Item', 2);invoke(sheet2, 'Activate');% Get a handle to the active sheetActivesheet = Excel.Activesheet;% Put a MATLAB array into ExcelA = [1 2; 3 4];ActivesheetRange = get(Activesheet,'Range','A1:B2');set(ActivesheetRange, 'Value', A);% Get back a range. It will be a cell array,% since the cell range can% contain different types of data.Range = get(Activesheet, 'Range', 'A1:B2');B = Range.value;% Convert to a double matrix. The cell array must contain only scalars.B = reshape([B{:}], size(B));% Now save the workbookinvoke(Workbook, 'SaveAs', 'myfile.xls');% To avoid saving the workbook and being prompted to do so,% uncomment the following code.% Workbook.Saved = 1;% invoke(Workbook, 'Close');% Quit Excelinvoke(Excel, 'Quit');% End processdelete(Excel);There are several options for connecting MATLAB with Excel.
