Method Detail

upper

public static boolean upper(D1Submatrix64F T)

lower

public static boolean lower(D1Submatrix64F T)

upper

public static boolean upper(double[] T,
            int indexT,
            int n)

Performs an inline upper Cholesky decomposition on an inner row-major matrix. Only the upper triangular portion of the matrix is read or written to.

Parameters:

T - Array containing an inner row-major matrix. Modified.

indexT - First index of the inner row-major matrix.

n - Number of rows and columns of the matrix.

Returns:

If the decomposition succeeded.

lower

public static boolean lower(double[] T,
            int indexT,
            int n)

Performs an inline lower Cholesky decomposition on an inner row-major matrix. Only the lower triangular portion of the matrix is read or written to.

Parameters:

T - Array containing an inner row-major matrix. Modified.

indexT - First index of the inner row-major matrix.

n - Number of rows and columns of the matrix.

Returns:

If the decomposition succeeded.
