Data Import/export from figure Matlab GUI

Hello, I need to analyze some data for experiment. So, I read the data from .txt file into the Matlab GUI and plotted a figure in log scale. Now, How can I return the data into Excel file/Notepad from the plotted figure of Matlab GUI. Can anybody help me?

Thanks..... D Bhuiyan

After processing your original data, you can use xlswrite() or dlmwrite() or csvwrite() to write the data to a file. For more flexible output, you need to use fopen(), fprintf(),fclose(). Check the help for sprintf() to find out the output format.

Simple example if you just want to output a regular numerical matrix.

xlswrite('test.xls', rand(3,4));
csvwrite('test.csv',rand(4,5);

xlswrite() is straightforward. Did you try the above example? If you have numerical data mixed with strings, you can use cell array.

c={'ab',1 4;400,0.4,'akdjf'};

xlswrite('test.xls',c);
