Praveen - please clarify what you mean by the common between them. Do the structures have fields that you want to compare? Or something else? Please provide a small example.
For example
structure 1='field1','field2','field3';
structure 2='field1','field4','field3';
The common between them is field1 and field 3 and i want to write that in structure 1.

structure_1={'field1','field2','field3'};
structure_2={'field1','field4','field3'};
structure_1=intersect(structure_1,structure_2)

common_fields = intersect( fieldnames(structure1), fieldnames(structure2));
for fn = common_fields
this = fn{1};
new_struct(1).(this) = structure1.(this);
new_struct(2).(this) = structure2.(this);
end
