Hello Sir/Madam,
I am using gsl to find the inverse of the matrix. I have that done in a
routine, which is called in a for loop.
When it goes to 5th iteration, some of the inverse values go to "nan." Until
4th iteration, the inverse values are perfect. Could you please help me with
what could be going wrong. I tried to plug in some small integer numbers for a
2x2 matrix and find out what happens at 5th iteration. I observe that no matter
what the matrix values are, the inverse for column 2 are all nan.
Your help will be really appreciated.
Thanks,
Student.
