  • Method Details

    • mult

      void mult(CRMatrix<T> a, CRMatrix<T> b, CRMatrix<T> out)
      Performs matrix multiplication. out = a*b

    • addTo

      void addTo(CRMatrix<T> dst, CRMatrix<T> src)
      Adds src into dst. Needed when a value feeds more than one consumer and the derivatives arriving from each have to be summed

    • diag

      void diag(double value, CRMatrix<T> m)
      Fills the diagonal elements with the specified value

    • zero

      default void zero(CRMatrix<T> m)
      Fills all elements in the matrix with zero

    • fill

      void fill(CRMatrix<T> m, double value)
      Fills every element with the specified value

    • zero

      void zero(CRArray<T> m, int length)
      Fills all elements in the array with zero

    • random

      void random(Random rand, double min, double max, CRMatrix<T> output)
      Fills the matrix with uniformly distributed random values.
      Parameters:
      rand - Random number generator
      min - Lower extent of random values
      max - Upper extent of random values
      output - Matrix which is filled

    • random

      Creates a matrix with random values

    • random

      CRArray<T> random(Random rand, double min, double max, int length)
      Creates a random array

    • isUncountable

      boolean isUncountable(CRMatrix<T> m)
      Returns true if the matrix contains at least one uncountable number

    • createArray

      CRArray<T> createArray(int length)
      Allocates a new array with the specified length

    • createMatrix

      CRMatrix<T> createMatrix(int rows, int cols)
