an integer value, the dimension of the square matrix.
Details
The function pascal generates a Pascal matrix of order n
which is a symmetric, positive, definite matrix with integer entries
made up from Pascal's triangle. The determinant of a Pascal matrix is 1.
The inverse of a Pascal matrix has integer entries. If lambda
is an eigenvalue of a Pascal matrix, then 1/lambda is also an
eigenvalue of the matrix. Pascal matrices are ill-conditioned.
