hgexport(gcf, 'fft_data%d.jpg', index, hgexport('factorystyle'), 'format', 'jpeg'); whats wrong in this line ? in matlab

This line of code is attempting to export the current figure (gcf) to a JPEG image file named fft_data%d.jpg, where %d is a placeholder for a number specified by the variable index. However, the issue with this line is the format specifier %d followed by "jpg". This notation is incorrect for string formatting in MATLAB.

To fix this issue, you can use sprintf to create a properly formatted file name string. Here's how you can modify the line of code to correct the issue:

main.m
fileName = sprintf('fft_data%d.jpg', index);
hgexport(gcf, fileName, hgexport('factorystyle'), 'format', 'jpeg');

3 lines

This code snippet will create a valid file name using sprintf and then export the figure using the corrected file name.

Corrected line:

main.m
fileName = sprintf('fft_data%d.jpg', index);
hgexport(gcf, fileName, hgexport('factorystyle'), 'format', 'jpeg');
