Read Microsoft Excel spreadsheet file. The xlsread ignores leading rows or columns of text. However, if a cell not in a leading row or column is empty or contains text, xlsread puts a NaN in its place in the return array, num. If your system does not have this capability, the xlsread syntax that passes the 'basic' keyword is recommended.
The identifiers reserved for standard input, output, and error are not included. The number of elements in the vector is equal to the number of open files. The output filename is resolved to the full path.
The fopen function does not read information from the file to determine the output value. If the file was opened in binary mode, permission includes the letter 'b'.
The encodingOut output is a standard encoding scheme name. An invalid fileID returns empty character vectors for all output arguments. Open the file, airfoil.
Then, close the file. If fopen cannot open the file, display the relevant error message. Your results might differ. Input Arguments filename — Name of file to open character vector or string scalar Name of the file to open, including the file extension, specified as a character row vector or a string scalar.
If the file is not in the current folder, filename must include a full or a relative path. If you open a file with read access and the file is not in the current folder, then fopen searches along the MATLAB search path. If you open a file with write or append access and the file is not in the current folder, then fopen creates a file in the current directory.
File access type, specified as a character vector or a string scalar. You can open a file in binary mode or in text mode. On UNIX systems, both translation modes have the same effect. To open a file in binary mode, specify one of the following.XLSWRITE alternative XLWRITE on a Mac. Learn more about xlswrite, xlwrite, mac.
- The following examples illustrate how to use XLSWRITE to add column and row labels to a MATLAB matrix that is written to an Excel file. This can be done either by writing to several sections of the worksheet (Case 1), or by joining the data and labels before writing to the XLS-file (Case 2).

Write Numeric and Text Data to Spreadsheet File. To export a numeric array and a cell array to a Microsoft ® Excel ® spreadsheet file, use the xlswrite function.
You can export data in individual numeric and text workspace variables to any worksheet in the file, and to any location within that worksheet. Input table, specified as a table or a timetable.
Each variable in tblA must be a valid input to sort or sortrows. Data Types: table You can access the dimension names of tblA using timberdesignmag.comionNames. before calling sortrows(A). In this case, MATLAB sorts the rows of .
