  • Constructor Details

    • PMMLRealMatrix

      public PMMLRealMatrix()

  • Method Details

    • get

      public abstract T get(int row, int col)
      Returns the value of the given matrix element
      Parameters:
      row - the row of the element
      col - the column of the element
      Returns:
      the value of the element

    • set

      public abstract void set(int row, int col, T value)
      Sets the value of the given matrix element. Setting to a row/column beyond the size of the matrix will automatically resize as-needed.
      Parameters:
      row - the row of the element
      col - the column of the element
      value - the value of the element

    • ensureSize

      public abstract PMMLRealMatrix<T> ensureSize(int numRows, int numCols)
      Sizes the matrix to the given number of rows and columns
      Parameters:
      numRows - the number of rows.
      numCols - the number of columns
      Returns:
      a "this" reference

    • getNumRows

      public abstract int getNumRows()
      Returns the number of rows in the matrix
      Returns:
      the number of rows in the matrix

    • getNumColumns

      public abstract int getNumColumns()
      Returns the number of columns in the matrix
      Returns:
      the number of columns in the matrix

    • parse

      public static <T extends Number> PMMLRealMatrix<T> parse(Element e)
      Parses the given matrix element
      Parameters:
      e - the element
      Returns:
      a matrix object

    • toPMML

      public abstract void toPMML(Element parent)
      Adds this matrix element as a child of the given element
      Parameters:
      parent - the parent element

    • getType

      public abstract Class<?> getType()
      Gets the numeric datatype of this matrix.
      Returns:

    • symmetric

      public static <T extends Number> PMMLRealMatrix<T> symmetric(Class<?> type)
      Creates a new symmetric matrix. Values set will automatically appear on both sides of the diagonal
      Returns:
      a new symmetric matrix

    • diagonal

      public static <T extends Number> PMMLRealMatrix<T> diagonal(Class<?> type)
      Creates a new diagonal matrix. Non-zero values may only be specified on the diagonal.
      Returns:
      a new diagonal matrix

    • dense

      public static <T extends Number> PMMLRealMatrix<T> dense(Class<?> type)
      Creates a new dense matrix
      Returns:
      a new dense matrix

    • sparse

      public static <T extends Number> PMMLRealMatrix<T> sparse(T diagDefault, T offDiagDefault)
      Creates a new sparse matrix
      Parameters:
      diagDefault - the default value for values on the diagonal
      offDiagDefault - the default value for values not on the diagonal
      Returns:
      a new sparse matrix

    • getFieldClass

      public static Class<?> getFieldClass(Class<?> clazz, String name)
