The message gives the size ofthe matrices involved.Matrix types are referred to by the following codes:<PRE> Matrix or vector Rect Symmetric matrix Sym Band matrix Band Symmetric band matrix SmBnd Lower triangular matrix LT Lower triangular band matrix LwBnd Upper triangular matrix UT Upper triangular band matrix UpBnd Diagonal matrix Diag Crout matrix (LU matrix) Crout Band LU matrix BndLU</PRE>Other codes should not occur.<P>See the section on<A HREF="except.html">exceptions</A> for more details on the structure ofthe exception classes.<P>I have defined a class Tracer that is intended to help locate the placewhere an error has occurred. At the beginning of a function I suggestyou include a statement like<PRE> Tracer tr("name");</PRE>where name is the name of the function. This name will be printed aspart of the error message, if an exception occurs in that function, orin a function called from that function. You can change the name as youproceed through a function with the ReName function<PRE> tr.ReName("new name");</PRE>if, for example, you want to track progress through the function.<P><A HREF="bugs.html"> next</A> - <A HREF="bugs.html"> skip</A> - <A HREF="index.html"> up</A> - <A HREF="index.html"> start</A><P></BODY></HTML>⌨️ 快捷键说明
