Hi everyone,
I'm getting a segfault error in a QR decomposition (used by a function of my own). I have been able to reproduce a problem in a simple program (compiled with gcc 4.4 and using eigen 3.1) . The program seems to work fine but valgrind complains about an 'Invalid read of size 8' error. v is a float array of size 2455 Mat is a float array of size 24550
Here is the valgrind output :
I'm quite new to the eigen library, so I may do something wrong. Have you got any ideas ? Thanks, Jean |
