Troubles with 14x14 matrix

I have been creating a 14 by 14 matrix on Matlab to help my assessment, but, when I keyed in the values long hand, I got an answer, yet when I keyed them in shorthand, the matrix produced replaced all the values with 1. Why is this?

leo - please clarify what you mean by short hand. Is the code that you have written or some other method? Also, rather than embedding a screen shot of your code, please attach the m-file so that we can more easily understand what it is doing.

short hand means, as shown above, creating constants for say mass or inertia, and putting them into the equation

It looks like A is classified as a logical variable. Try

A = double(A);

then change the values manually.
