1  %'sub_field': combines two input fields


2  %


3  % the two fields are subtstracted when of the same nature (scalar or


4  % vector), if the coordinates do not coincide, the second field is


5  % interpolated on the cooridintes of the first one


6  %


7  % when scalar and vectors are combined, the fields are just merged in a single matlab structure for common visualisation


8  %


9  % function SubData=sub_field(Field,XmlData,Field_1)


10  %


11  % OUPUT:


12  % SubData: structure representing the resulting field


13  %


14  % INPUT:


15  % Field: matlab structure representing the first field


16  % Field_1:matlab structure representing the second field
