Hi,

Currently I have two files; A and B.

File A has below data:-

-3 + <1 2 3 4 5 6 7 8 1 2 > - 1]
-2 + <8 8 3 4 0 3 7 9 1 3 > - 1]
-1 + <3 7 3 4 8 2 7 2 1 2 > - 1]
-3 + <2 2 3 4 3 1 7 8 8 2 > - 1]

and File B has below data:-
<9 1 1 4 2 6 3 8 8 9 >

From these two files, I try to do a cross product vector for these two files.
<1 2 3 4 5 6 7 8 1 2 >*<9 1 1 4 2 6 3 8 8 9 >
+<8 8 3 4 0 3 7 9 1 3 > *<9 1 1 4 2 6 3 8 8 9 >
+<3 7 3 4 8 2 7 2 1 2 > *<9 1 1 4 2 6 3 8 8 9 >
+<2 2 3 4 3 1 7 8 8 2 > *<9 1 1 4 2 6 3 8 8 9 >

Could anyone show me how I could extract the elements from these two files such as above?

As of now I could cat the file A but do not know how to extract elements from < on wards. And i do not know how I could perform division with elements form another file, file B.

Please help. Thanks alot.
