Function FLATTEN_SCAT

Package

Short description

Usage

    S = flatten_scat(S)

Input

    S (cell): A scattering representation.

Output

    S (cell): The same scattering representation, but flattened into one layer. As
       a result, meta fields from different orders are concatenated.
       Since different orders have meta fields of different sizes, such as meta.j,
       the meta fields are filled with  -1's where necessary.
function Y = flatten_scat(X)
	Y.signal = {};
	Y.meta = struct();
	Y.meta.order = [];
	meta_fields = fieldnames(X{end}.meta);
	r = 1;
	for m = 0:length(X)-1
		ind = r:r+length(X{m+1}.signal)-1;
		Y.signal(ind) = X{m+1}.signal;
		for p = 1:length(meta_fields)
			field = meta_fields{p};
			if isfield(Y.meta,field)
				value = getfield(Y.meta,field);
				value = [];
			if isfield(X{m+1}.meta,field)  : handle the case where 
				 different layer have different
				new_value = getfield(X{m+1}.meta,field);
				new_value = [];
			if size(value,1) < size(new_value,1)
				value = [value; ...
			elseif size(value,1) > size(new_value,1)
				new_value = [new_value; ...
			value = [value new_value];
			Y.meta = setfield(Y.meta,field,value);
		Y.meta.order = [Y.meta.order m*ones(1,length(ind))];
		r = r+length(ind);
	Y = {Y};
