Hi all,<div><br></div><div>I browsed the LinearSystemWrapper classes and I noticed that they are restricted for square matrices. There is a SetSystemOrder(unsigned int) method, which sets the row number and column number to the same value. Is this for a good reason? I assume that for example vnl_lsqr.* can handle the non-square cases as well. I write this, because I would like to use them in this way. </div>
<div><br></div><div>And how should one know that LinearSystemWrapperVNL or LinearSystemWrapperDenseVNL is the suitable one to use? How many zeros (percentage?) have to be in a matrix to define it as a sparse matrix?</div>
