I have a function in matlab.For ex,
%function [mean std]=size(data,channel)
i set data's filename=ET1_A(imported to workspace alrdy) and channel=2 (total no.channel=63), to find the mean and std of selected data(ET1_A),and I want to save the statistical feature into .mat form in the workspace as shown in below:
%savefile='ET1_A_stat.mat'; save(savefile,'mean','std')
However,if i choose another data like ET1_B,I need to change my code manually like: %savefile='ET1_B_stat.mat'; save(savefile,'mean','std')
Is there any good idea of using MATLAB's efficient code to change the filename automatically nicely?
Thanks

Don't use size() for the name of your function or you'll blow away the built in size() function.

let says the matrix ET1_A_l1=[1;2;1;3;1;4],channel=1 i run your code and the save file name is '1_Channel12_Channel13_Channel14.mat',how to make the data can be named to be ET1_A_l1??

DO you have a variable which would have the string 'ET1_A_I1' stored in it at that point? If you are loading files in a loop, then how did you figure out which file to load?
