Hi,
Some stuff below that may help. Also, there are
palletes to do this. File->Palettes->BasicTypesetting
In[23]:=
In[23]:= m={ {1, 2, 3}, {4, 5, 6} }
Out[23]= {{1, 2, 3}, {4, 5, 6}}
In[24]:= MatrixForm[m]
Out[24]//MatrixForm= 1 2 3
4 5 6
In[27]:= m1=AppendTo[m,{7,8,9}]
Out[27]= {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}
In[28]:= MatrixForm[m1]
Out[28]//MatrixForm= 1 2 3
4 5 6
7 8 9
In[29]:= m2=AppendTo[Transpose[m1], {a, b, c}]
Out[29]= {{1, 4, 7}, {2, 5, 8}, {3, 6, 9}, {a, b, c}}
In[30]:= MatrixForm[Transpose[m2]]
Out[30]//MatrixForm= 1 2 3 a
4 5 6 b
7 8 9 c
