    • leastSquares

      public static org.ejml.interfaces.linsol.LinearSolverDense<org.ejml.data.DMatrixRMaj> leastSquares​(int numRows, int numCols)
      Creates a good general purpose solver for over determined systems and returns the optimal least-squares solution. The A matrix will have dimensions (m,n) where m ≥ n.
      Parameters:
      numRows - The number of rows that the decomposition is optimized for.
      numCols - The number of columns that the decomposition is optimized for.
      Returns:
      A new least-squares solver for over determined systems.

    • symmPosDef

      public static org.ejml.interfaces.linsol.LinearSolverDense<org.ejml.data.DMatrixRMaj> symmPosDef​(int matrixWidth)
      Creates a solver for symmetric positive definite matrices.
      Returns:
      A new solver for symmetric positive definite matrices.
