Type in the correct filename

Question

I have a function in matlab.

function [MEAN STD]=result(data)
MEAN=mean(data);
STD=std(data);

savefilename=sprintf('%s',data)
save(savefilename,'MEAN','STD')
end

i set data's filename=ET1_A_l1(imported to workspace alrdy)(ET1_A_l1=[1;2;1;3;1;4] to find the mean and std of selected data(ET1_A_l1),and save the statistical feature into .mat form as shown in below:

>>[MEAN STD]=result(ET1_A_l1)

As a result, the name of save file is 121314.mat,and it is not 'ET1_A_l1',is there any good idea of using MATLAB's efficient code to change the filename correctly?

Thanks

What is your function, and how is it called? It looks quite mixed up in your question... — glglgl
i edit the function again but stil cannot save the correct name file .. — Tony YEe

If I understand correctly, you can use inputname, which gives you the name of the function argument in the callers workspace:

function result(data)
    display(['file name should be ' inputname(1)]);  % name of the first parameter
end

...

>> result(ET1_A_l1);
file name should be ET1_A_l1

Type in the correct filename
