I tried using the method "ecg". This is my error message, what I got. Undefined function 'ecg' for input arguments of type 'double'.
Now, I typed help ecg in the command window. This is what I got.
_ * *>> help ecg
ecg not found.
Use the Help browser search field to search the documentation, or type "help help" for help command options, such as help for methods.**_
What can I do to get rid of this problem? I tried it, to use it in my code.

The message means, that you do not have a function called "ecg" in your path. Why do you assume, that this function exists?

@Jan Simon: Yes...google leads to the link exchange. There is no documentation in google. Which says MATLAB\R2015a\toolbox\signal\sigdemos\ecg.m

Ah, yes, thanks. Then this command is a part of the demos and therefore it is not documented in Matlab's online docs. This detail might solve the OP's problem:
Buy and install the signal processing toolbox, then this command appears in the demos.
I think this discussion might solve the question. +1
