/* Purpose */
/* ======= */
/* SGGSVD computes the generalized singular value decomposition (GSVD) */
/* of an M-by-N float matrix A and P-by-N float matrix B: */
/* U'*A*Q = D1*( 0 R ), V'*B*Q = D2*( 0 R ) */
/* where U, V and Q are orthogonal matrices, and Z' is the transpose */
/* of Z. Let K+L = the effective numerical rank of the matrix (A',B')', */
/* then R is a K+L-by-K+L nonsingular upper triangular matrix, D1 and */
/* D2 are M-by-(K+L) and P-by-(K+L) "diagonal" matrices and of the */
/* following structures, respectively: */
/* If M-K-L >= 0, */
/* K L */
/* D1 = K ( I 0 ) */
/* L ( 0 C ) */
/* M-K-L ( 0 0 ) */
/* K L */
/* D2 = L ( 0 S ) */
/* P-L ( 0 0 ) */
/* N-K-L K L */
/* ( 0 R ) = K ( 0 R11 R12 ) */
/* L ( 0 0 R22 ) */
/* where */
/* C = diag( ALPHA(K+1), ... , ALPHA(K+L) ), */
/* S = diag( BETA(K+1), ... , BETA(K+L) ), */
/* C**2 + S**2 = I. */
/* R is stored in A(1:K+L,N-K-L+1:N) on exit. */
/* If M-K-L < 0, */
/* K M-K K+L-M */
/* D1 = K ( I 0 0 ) */
/* M-K ( 0 C 0 ) */
/* K M-K K+L-M */
/* D2 = M-K ( 0 S 0 ) */
/* K+L-M ( 0 0 I ) */
/* P-L ( 0 0 0 ) */
/* N-K-L K M-K K+L-M */
/* ( 0 R ) = K ( 0 R11 R12 R13 ) */
/* M-K ( 0 0 R22 R23 ) */
/* K+L-M ( 0 0 0 R33 ) */
/* where */
/* C = diag( ALPHA(K+1), ... , ALPHA(M) ), */
/* S = diag( BETA(K+1), ... , BETA(M) ), */
/* C**2 + S**2 = I. */
/* (R11 R12 R13 ) is stored in A(1:M, N-K-L+1:N), and R33 is stored */
/* ( 0 R22 R23 ) */
/* in B(M-K+1:L,N+M-K-L+1:N) on exit. */
/* The routine computes C, S, R, and optionally the orthogonal */
/* transformation matrices U, V and Q. */
/* In particular, if B is an N-by-N nonsingular matrix, then the GSVD of */
/* A and B implicitly gives the SVD of A*inv(B): */
/* A*inv(B) = U*(D1*inv(D2))*V'. */
/* If ( A',B')' has orthonormal columns, then the GSVD of A and B is */
/* also equal to the CS decomposition of A and B. Furthermore, the GSVD */
/* can be used to derive the solution of the eigenvalue problem: */
/* A'*A x = lambda* B'*B x. */
/* In some literature, the GSVD of A and B is presented in the form */
/* U'*A*X = ( 0 D1 ), V'*B*X = ( 0 D2 ) */
/* where U and V are orthogonal and X is nonsingular, D1 and D2 are */
/* ``diagonal''. The former GSVD form can be converted to the latter */
/* form by taking the nonsingular matrix X as */
/* X = Q*( I 0 ) */
/* ( 0 inv(R) ). */

/* Purpose */
/* ======= */
/* SGGSVD computes the generalized singular value decomposition (GSVD) */
/* of an M-by-N real matrix A and P-by-N real matrix B: */
/* U'*A*Q = D1*( 0 R ), V'*B*Q = D2*( 0 R ) */
/* where U, V and Q are orthogonal matrices, and Z' is the transpose */
/* of Z. Let K+L = the effective numerical rank of the matrix (A',B')', */
/* then R is a K+L-by-K+L nonsingular upper triangular matrix, D1 and */
/* D2 are M-by-(K+L) and P-by-(K+L) "diagonal" matrices and of the */
/* following structures, respectively: */
/* If M-K-L >= 0, */
/* K L */
/* D1 = K ( I 0 ) */
/* L ( 0 C ) */
/* M-K-L ( 0 0 ) */
/* K L */
/* D2 = L ( 0 S ) */
/* P-L ( 0 0 ) */
/* N-K-L K L */
/* ( 0 R ) = K ( 0 R11 R12 ) */
/* L ( 0 0 R22 ) */
/* where */
/* C = diag( ALPHA(K+1), ... , ALPHA(K+L) ), */
/* S = diag( BETA(K+1), ... , BETA(K+L) ), */
/* C**2 + S**2 = I. */
/* R is stored in A(1:K+L,N-K-L+1:N) on exit. */
/* If M-K-L < 0, */
/* K M-K K+L-M */
/* D1 = K ( I 0 0 ) */
/* M-K ( 0 C 0 ) */
/* K M-K K+L-M */
/* D2 = M-K ( 0 S 0 ) */
/* K+L-M ( 0 0 I ) */
/* P-L ( 0 0 0 ) */
/* N-K-L K M-K K+L-M */
/* ( 0 R ) = K ( 0 R11 R12 R13 ) */
/* M-K ( 0 0 R22 R23 ) */
/* K+L-M ( 0 0 0 R33 ) */
/* where */
/* C = diag( ALPHA(K+1), ... , ALPHA(M) ), */
/* S = diag( BETA(K+1), ... , BETA(M) ), */
/* C**2 + S**2 = I. */
/* (R11 R12 R13 ) is stored in A(1:M, N-K-L+1:N), and R33 is stored */
/* ( 0 R22 R23 ) */
/* in B(M-K+1:L,N+M-K-L+1:N) on exit. */
/* The routine computes C, S, R, and optionally the orthogonal */
/* transformation matrices U, V and Q. */
/* In particular, if B is an N-by-N nonsingular matrix, then the GSVD of */
/* A and B implicitly gives the SVD of A*inv(B): */
/* A*inv(B) = U*(D1*inv(D2))*V'. */
/* If ( A',B')' has orthonormal columns, then the GSVD of A and B is */
/* also equal to the CS decomposition of A and B. Furthermore, the GSVD */
/* can be used to derive the solution of the eigenvalue problem: */
/* A'*A x = lambda* B'*B x. */
/* In some literature, the GSVD of A and B is presented in the form */
/* U'*A*X = ( 0 D1 ), V'*B*X = ( 0 D2 ) */
/* where U and V are orthogonal and X is nonsingular, D1 and D2 are */
/* ``diagonal''. The former GSVD form can be converted to the latter */
/* form by taking the nonsingular matrix X as */
/* X = Q*( I 0 ) */
/* ( 0 inv(R) ). */
