f this array contains the
          upper / lower trapezoidal ICC factor.
          On exit, if INFO = 0 and P &gt; 0, then the leading
          (S+1)*K-by-(N-P+1)*K / (N-P+1)*K-by-(S+1)*K part of this
          array contains the upper / lower trapezoidal part of the
          P-th to (P+S)-th block rows / columns of the ICC factor.
          The elements in the strictly lower / upper trapezoidal
          part are not referenced.

  LDR     INTEGER
          The leading dimension of the array R.
