Unhandled Exception 0xc0000005 Access Violation


Arrays in C++ start at 0, and if you're trying to make them start at 1, well, I suggest you don't do it. Once you rewrite the code and remove all of those calls to new[] and delete[], those std::bad_alloc calls will disappear. This implies that the functions like getNumRows, getNumColumns, and getElement should be const as well, as such: class Matrix2D { //....

Unhandled Exception 0xc0000005 Access Violation

A few rebus puzzles Origin of "queer as a clockwork orange" how to stop muting nearby strings or will my fingers reshape after some practice? The program that I am writing currently has one class that will eventually be used to draw menus, using a library that my university has written themselves named Gwin. You can double click in the call stack window to move around in the call chain to check the value of local variables. What is the value of K?

I've noticed that something is wrong because when I tried to use 2048 or 4096, etc I didn't see any difference for a Fortran test application I used.

Unhandled Exception Access Violation Reading Location Thanks.

Hope it works. But I need these throughout the analysis so can't delete them. As to using new[], I would suggest you change to std::vector<> instead of using new[]/delete[]. for(int i=1; i<=a.getNumRows(); i++) { for(int j=1; j<=a.getNumColumns(); j++) { transpose.setElement(j, i, a.getElement(i, j)); } } //no need to return anything because transpose will store the output. } I'm slowly integrating

But after I run the program agin without any change, it again stops at my recursive subroutine as it was in first time.

I'd leave that open while you run the program and if it goes up and up and up and gets to the top and then crashes then you've found the problem Thanks Mike_2000_17 for your really detailed reply.

That's the only way to know whether this is a memory leak issue, or a heap corruption issue. http://justjoomla.net/access-violation/unhandled-exception-c-access-violation.html Thanx for the reply.

Set values Stack Commit = 536870912 and Stack Reserved = 536870912, and Heap Commit = 536870912 and Heap Reserved = 536870912 Note: 536870912 = 2^29 / you could use even higher Is it because of "out-of-memory" ? But the problem is still the same. 0xc0000005: Access Violation Reading Location 0x00000000. Second, why are you writing C++ as if it's Fortran, where all your variables are capitalized?

I think I'd have to try it myself to see if I get the same here, but I'd need the gwin.h and it's .cpp or .lib file. And for you matrices, store them in one contiguous memory block (not array of arrays, but one big array).

By using new[]/delete[] you've moved the focus away from the real goal of computing eigenvalues and into the realm of pointer manipulation, memory management, etc.. I'll get onto google about the profiler. That maybe more worthwhile then taking something from a general algorithm implementation (probably geared toward Fortran or Algol) and do a line-by-line translation to C++, which seems like what you tried I see a lot of loops, and if they depend on arrays starting at 1, then you're practically begging for memory corruption issues.

I have used new operator to allocate them. What would be your next deduction in this game of Minesweeper? Thanks in advance. I can rate my self in python as begineer.

The functions/classes might be trying to delete them or possibly use them after they are destroyed.
