write into an excel file in matlab

To write data into an Excel file in MATLAB, we can use the built-in writematrix function. However, this function only works if you have Microsoft Excel installed and if you have a license for it.

Alternatively, we can use the csvwrite function which writes data to a CSV file that can be opened with Microsoft Excel.

Example using writematrix function:

main.m
% Create sample data
data = [1 2 3; 4 5 6; 7 8 9];

% Write data to Excel file
filename = 'data.xlsx';
writematrix(data, filename);
132 chars
7 lines

Example using csvwrite function:

main.m
% Create sample data
data = [1 2 3; 4 5 6; 7 8 9];

% Write data to CSV file
filename = 'data.csv';
csvwrite(filename, data);
126 chars
7 lines

In both cases, the file will be saved in the current MATLAB directory unless you specify a different directory in the filename.
