Convert a tab separated file using bash

Dear all,

I have a file in this format (like a matrix)
- A B C .. X
A 1 4 2 .. 2
B 2 6 4 .. 8
C 3 5 5 .. 4
. . . ... .
X . . ... .

and want to convert it into a file with this format:
A A = 1
A B = 4
A C = 2
...
A X = 2
B A = 2
B B = 6
etc

1) numbers and letters are separated with a tab
2) dots in the example represent numbers or letters

Is there an easy way in bash to make this conversion?

Thanks
