How do I differentiate two matricies with HP 50G or HP 49G?  Hewlett Packard
This is a discussion on How do I differentiate two matricies with HP 50G or HP 49G?  Hewlett Packard ; Hello,
i have a question to a matrix operation with the HP 50G and/or HP 49G.
How do I differentiate two matricies? I donīt mean "matrix minus
matrix"!
Example:
[[1,2,3,4][5,6,7,8][1,2,3,4][5,6,7,8]]>a
delta(a) = [[4,4,4,4][4,4,4,4][4,4,4,4]]
Is there a possibility? With the TI89 ...

Hello,
i have a question to a matrix operation with the HP 50G and/or HP 49G.
How do I differentiate two matricies? I donīt mean "matrix minus

delta(a) = [[4,4,4,4][4,4,4,4][4,4,4,4]]
Is there a possibility? With the TI89 that is possible!

I assume you mean:
[[Row2Row1][Row3Row2][Row4Row3]]
> [[1,2,3,4][5,6,7,8][1,2,3,4][5,6,7,8]]>a
If this matrix is on the stack then this program should work:
\<< AXM 2 \<< SWAP  \>> DOSUBS AXM \>>

Unfortunately that does not function! I tried it several times.

Oops! My bad, it should have been:
\<< AXL 2 \<< SWAP  \>> DOSUBS AXL \>>

Thank you, Robert!!
It works!
