Hi all,

A := [[1,2],[3,4]];

A1:=convert(A, Matrix);

 

I am very happy with conversion between Matrices and Vectors.

However, I does not seem to be able to do this backwards to [row] or [column] Vectors???

Say how do I get back to A from A1???

 

I tried to use

convert(A1,Vector);

convert(A1,Vector[row]);

convert(A1,Vector[row],2);

 

And many others...

Help system is basically useless...

 

Also, how would I get

[[1,3],[2,4]];

???? This is "by column" in this case.

 

Thanks!
