Hi, I have 3 components which are struct type and I would like to apply a threshold using wthresh. My problem is that wthresh function doesn't accept a struct in input parameter. How can I do that ? Thanks for your answers

A structure is simply a container for several variables (the fields of the structure). 'Thresholding a structure' does not mean anything. So, you need to be clearer about what you want to do.
You may want to threshold all the fields of the structure, or just one (which one?).

structfun(), probably with 'Uniform', 0

I don't really understand how structfun() works. I have my Component which is a struct, I do
structfun(wthresh(Component1,'s',T),'UniformOutpout',false);
But it always the same problem, "Undefined function 'abs' for input arguments of type 'struct'." Thanks for your answer

structfun(@(field) wthresh(field, 's', T), Component1, 'Uniform', 0)
