Sorry if these are answered in a FAQ file, I could not find any FAq file for this group. Math. 4.0, windows95. 1. I do a lot of calculation in a notebook, save it, then when I restart Math & open the file I have to recalculate each item before I can resume where I left off. Is there any way to tell Math to recalculate everything when the file is reopened? 2. I enter a matrix as (say) A={{1,2,3},{4,5,6} etc and it displays in that form. Is there any way to make Math display matrices as matrices? I know you can do B=A.A//MatrixForm this looks right but Math doesnt know this is a matrix. So I would like matrices to be held internally in list form but displayed in matrix form. 3. and finally, is there any way to export the matrix into Excel?
