Hello, I have been a test of MSE.
I am currently experimenting with using the Find function.
I sometimes following error occurs during repeated experiments with the wrong MSE results
Empty matrix: 1-by-0
http://jp.mathworks.com/help/matlab/ref/find.html
So, I modify the code as follows.
h_DSiidkukeiseisu = h_DSiidkukei * 1000; %少数点を整数化
[h_DSiidkukeiTk]= find((abs(h_DSiidkukeiseisu))>=1); %Tk_DS%浮動小数点の丸め誤差が原因を防ぐ
But it seems there is a problem yet.
I need to find a value of the vector(non-zero).
Please check the code.

I missed 0 for 1000. I revised the code. h_DSiidkukei * 10000

Your code is not looking for non-zeros. Your code is looking for locations where the absolute value is at least 1. That is not going to find anything if all of the values are zero, or if all of the non-zero values have absolute value less than 1.
