Class SparseDComplexMatrix1D

    • Constructor Detail

      • SparseDComplexMatrix1D

        public SparseDComplexMatrix1D(double[] values)
        Constructs a matrix with a copy of the given values. The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa.
        Parameters:
        values - The values to be filled into the new matrix.
      • SparseDComplexMatrix1D

        public SparseDComplexMatrix1D(int size)
        Constructs a matrix with a given number of cells.
        Parameters:
        size - the number of cells the matrix shall have.
        Throws:
        IllegalArgumentException - if size<0.
    • Method Detail

      • assign

        public DComplexMatrix1D assign(double[] value)
        Description copied from class: DComplexMatrix1D
        Sets all cells to the state specified by values. values is required to have the same number of cells as the receiver. Complex data is represented by 2 double values in sequence: the real and imaginary parts, i.e. input array must be of size 2*size().

        The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa.

        Overrides:
        assign in class DComplexMatrix1D
        Parameters:
        value - the values to be filled into the cells.
        Returns:
        this (for convenience only).
      • cardinality

        public int cardinality()
        Description copied from class: DComplexMatrix1D
        Returns the number of cells having non-zero values; ignores tolerance.
        Overrides:
        cardinality in class DComplexMatrix1D
        Returns:
        the number of cells having non-zero values.
      • getQuick

        public double[] getQuick(int index)
        Description copied from class: DComplexMatrix1D
        Returns the matrix cell value at coordinate index.

        Provided with invalid parameters this method may return invalid objects without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds. Precondition (unchecked): index<0 || index>=size().

        Specified by:
        getQuick in class DComplexMatrix1D
        Parameters:
        index - the index of the cell.
        Returns:
        the value of the specified cell.
      • index

        public long index(int rank)
        Description copied from class: AbstractMatrix1D
        Returns the position of the element with the given relative rank within the (virtual or non-virtual) internal 1-dimensional array. You may want to override this method for performance.
        Overrides:
        index in class AbstractMatrix1D
        Parameters:
        rank - the rank of the element.
      • like

        public DComplexMatrix1D like(int size)
        Description copied from class: DComplexMatrix1D
        Construct and returns a new empty matrix of the same dynamic type as the receiver, having the specified size. For example, if the receiver is an instance of type DenseDComplexMatrix1D the new matrix must also be of type DenseDComplexMatrix1D. In general, the new matrix should have internal parametrization as similar as possible.
        Specified by:
        like in class DComplexMatrix1D
        Parameters:
        size - the number of cell the matrix shall have.
        Returns:
        a new empty matrix of the same dynamic type.
      • like2D

        public DComplexMatrix2D like2D(int rows,                      int columns)
        Description copied from class: DComplexMatrix1D
        Construct and returns a new 2-d matrix of the corresponding dynamic type, entirely independent of the receiver. For example, if the receiver is an instance of type DenseDComplexMatrix1D the new matrix must be of type DenseDComplexMatrix2D.
        Specified by:
        like2D in class DComplexMatrix1D
        Parameters:
        rows - the number of rows the matrix shall have.

        Specified by:
        reshape in class DComplexMatrix1D
