I believe the only solution is a vector of (shared) pointers.  You could iterate through the sub matrices and add them to the vector with push_back or .reset<br><br>Also note that with a smart pointer, you can still easily use bind to execute STL algorithms on the collection/member functions.  See the example in:<br>

Hi All!<br>
<br>
I want to create STL collection of &quot;sub matrices&quot; of one bigger matrix.<br>
I tried the &quot;matrix_range&lt;matrix&lt;double&gt; &gt;&quot; but the matrix_range object don&#39;t have default constructor.<br>
<br>
Please recomend me how to create mapping to data in such case?<br>
<br>
Thanks!<br>
<br>
