4 % DESCRIPTION: STRUCT2OBJ converts a structure to the wanted object.
5 %
6 % CALL: objs = struct2obj(struct, class_name)
7 % objs = struct2obj(struct)
8 %
9 % If the class type is not specified, then the fieldnames of the input
10 % structure are compared to the fieldnames of all LTPDA classes until a
11 % matching class is found.
12 %
13 % INPUTS: struct: Structure which should be converted
14 % class_name: Class name
15 %
16 % OUTPUTS: objs: Vector of the wanted objects.
