sets if it should internally save the w matrix before performing the decomposition . must be set before decomposition the matrix . saving w can result in about a 5 % savings when solving systems around a height of 5k . the price is that it needs to save a matrix the size of the input matrix . concode_field_sep D1Submatrix64F A concode_elem_sep boolean saveW concode_elem_sep BlockMatrix64F dataW concode_elem_sep BlockMatrix64F dataWTA concode_elem_sep D1Submatrix64F Y concode_elem_sep int blockLength concode_elem_sep D1Submatrix64F W concode_elem_sep BlockMatrix64F dataA concode_elem_sep double temp[] concode_elem_sep D1Submatrix64F WTA concode_elem_sep double gammas[] concode_field_sep void setW concode_elem_sep void applyQ concode_elem_sep void applyQ concode_elem_sep boolean decompose concode_elem_sep void setup concode_elem_sep BlockMatrix64F getQ concode_elem_sep BlockMatrix64F getQR concode_elem_sep BlockMatrix64F initializeQ concode_elem_sep BlockMatrix64F getR concode_elem_sep boolean inputModified concode_elem_sep void applyQTran concode_elem_sep void updateA
