Information

  X*A = B

Due to symmetrie, Matrix A is uniquely defined by a triangle, i.e. the upper or the lower triangular matrix. It is assumed, that the input to describe A is either a Cholesky factor or part of matrix A itself. This is defined by the user with the boolean inputs isCholesky and upper which is true when A is already Cholesky factor and when A is upper triangular respectively.

         T
  A = L*L

       T
  X*L*L = B

Interface

function solveSymRight
  extends Modelica.Icons.Function;
  import MatricesMSL = Modelica.Math.Matrices;
  input Real A[:, size(A, 1)] "Matrix A of X*A = B";
  input Real B[:, :] "Matrix B of X*op(A) = B";
  input Boolean isCholesky = false "True if the A is already lower Cholesky factor";
  input Boolean upper = false "True if A is upper triAngular";
  output Real X[size(B, 1), size(B, 2)] = B "Matrix X such that X*A = B";
end solveSymRight;
