How to customize print file name with function input

I have a function including following input items: Filepath, NsperBatch, K. And I would like to use them as part of filename when saving a plot:

    print('Magnitude (dB) vs Time vs Frequency Collected in %d RF_bin with Batch %d Avg %d',Filepath,NsperBatch,K,'-dpng');

Receiving some errors as followings:

Error using checkArgsForHandleToPrint
Handle input argument contains nonhandle values.

Error in checkArgsForHandleToPrint

Error in print>LocalCreatePrintJob (line 216)
    handles = checkArgsForHandleToPrint(0, varargin{:});

Error in print (line 38)
    [pj, inputargs] = LocalCreatePrintJob(varargin{:});

Error in processAverna (line 93)
print('Magnitude (dB) vs Time vs Frequency Collected in %d RF_bin with Batch %d
Avg %d',Filepath,NsperBatch,K,'-dpng');___

filename = sprintf('Magnitude (dB) vs Time vs Frequency Collected in %d RF_bin with Batch %d Avg %d',Filepath,NsperBatch,K);
print(filename , '-dpng')

thanks, it works. However, the input path is too long and I need to short it to just the lowest level. Do you have any tip for that? thanks!

I notice that you have a variable named FilePath but you use a %d format specifier for it. That is confusing: I would have expected a %s format specifier.

If you have a qualified file name and want to get just the last part of the name, then

[~, basename, ext] = fileparts(filePath);

then use either basename by itself or [basename ext]

Great, thanks! I have updated the code accordingly.
