open excel file with write permission in matlab

To open an Excel file with write permission in MATLAB, you can use the xlsread and xlswrite functions. Here's an example code that opens an existing Excel file named "example.xlsx" with write permission and writes some data to it:

main.m
% Open the file in write mode
[~,~,raw] = xlsread('example.xlsx');
xlswrite('example.xlsx', [raw; {'New Data'}]);

% Add data to the file
newData = {'John', 25; 'Jane', 30};
xlswrite('example.xlsx', newData, 'Sheet1', 'A3:B4');
228 chars
8 lines

This code first uses the xlsread function to read the existing data in the file, and then appends a new row of data to it. Then it uses the xlswrite function to add a new sheet to the file and write some new data to it.

Note that you need to have Microsoft Excel installed on your computer for this code to work.
