Matrix operations

Mathematica allows to perform operations on the matrices. You can
build a matrix using the Table function for example.

	In[10]:= A = Table[i+j,{i,2},{j,2}]

	Out[10]= {{2, 3}, {3, 4}}

You can use the functions Det, Transpose and Inverse to find the
determinant, transpose and the inverse of the matrix A respectively.

	In[16]:= Det[A]

	Out[16]= -1

	In[17]:= Transpose[A]

	Out[17]= {{2, 3}, {3, 4}}

	In[18]:= Inverse[A]

	Out[18]= {{-4, 3}, {3, -2}}

Also, you could find the eigen values for the matrices using the
function 'Eigenvalues'.
