I have used spectrogram command to view mfcc. I used command "savsas" to sava it in image format. But when i oped it, fig shows xlabel, ylable and colorbar also. i need only imagein terms of pixel. i also tried imwrite, but it was black & white image.

As per my understanding, you have used ‘spectogram’ to view mfcc of audio frame and saved it as an image using ‘saveas’. However, you want to save only the spectrogram without any colorbar, xlabel and ylabel.
In order to remove the xlabel and ylabel, you can hide the axes by setting the ‘Visible’ property of the axes to ‘off’. You can use ‘colorbar’ command to delete the colorbar in the axes. Then you can save the spectrogram by using ‘saveas’, as shown below,
set(gca, 'Visible', 'off')
This will save the spectrogram without the colorbar and axes.
For more information, please refer to the following documentation,
I hope this resolves the issue.
