[876]  1  %'sub_field': combines two input fields, taking the difference if of the same nature


[519]  2  %


[876]  3  % the two fields are subtracted when of the same nature (scalar or


 4  % vector),and defined at the same points


[519]  5  %


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

 10  % OUPUT:


 11  % SubData: structure representing the resulting field


 12  %


 13  % INPUT:


 14  % Field: matlab structure representing the first field


 15  % Field_1:matlab structure representing the second field
