I found a way to create a double-matrix. <br /><br />"MatrixStore<Double> a = PrimitiveDenseStore.FACTORY.makeEye(4,4); " <br />"BasicMatrix b = new PrimitiveMatrix(a);"<br /><br />But how can I create a float-matrix? I know, that there are many factories, which expect a type of Number, like double or float. But if I set Float, I get only errors. <br /><br />Nice would be a short tutorial how to deal with float-matrices in ojaglo. I will need functions like add, mult and invert. And the initialization should be possible with a 2-dimensional-float-array, or something like that.<br /><br />Thanks for your help<br />Birgit<br /><br /><br /></div> <br><br><table cellpadding="0" cellspacing="0" border="0"><tr><td bgcolor="#000000"><img src="https://img.web.de/p.gif" width="1" height="1" border="0" alt="" /></td></tr><tr><td style="font-family:verdana; font-size:12px; line-height:17px;">Neu: WEB.DE De-Mail - Einfach wie E-Mail, sicher wie ein Brief! <br>Jetzt De-Mail-Adresse reservieren: https://produkte.web.de/go/demail02</td></tr></table> </body> |
