Output

This function uses the following arguments for output:

• A - Upon exit, the contents of A are destroyed.

• E - S3L array handle describing a real parallel array with rank(E) = rank(A) -1. axis1 of E must have the same extent as axis1 of A. The remaining axes are instance axes matching those of A in order of declaration and extents. Thus, each vector f within E corresponds to a matrix b within A.

• On return, each f contains the eigenvalues of the corresponding matrix b.

• V - S3L array handle describing a parallel array with the same rank, extents, and data type as A. For each instance matrix b within A, there is a corresponding two-dimensional array, w, within V. axis1 denotes the axis of V that contains the rows of w; axis2 denotes the axis of V that contains the columns of w.

On return, each column of w will contain an eigenvector of w.

• J - S3L array handle describing an integer parallel array with rank(J) = rank(A) - 1. axis1 of J should have an extent of 2. The remaining axes are instance axes matching those of A in order of declaration and extents. Thus, J will contain vectors of length 2 corresponding to the matrices b embedded within A.

On return, the first element of each vector will contain the number of eigenvalues found. The second element of each vector will contain the number of eigenvectors found.

• ier (Fortran only) - When called from a Fortran program, this function returns error status in ier.
