Math::GSL::Errno - Error Handling

    use Math::GSL::Errno qw/:all/;
    gsl_set_error_handler_off();
    print gsl_strerror($GSL_EDOM) . "\n";

$GSL_SUCCESS
Success
$GSL_FAILURE
General Failure
$GSL_CONTINUE
Iteration has not converged
$GSL_EDOM
Domain error; used by mathematical functions when an argument value does not fall into the domain over which the function is defined (like EDOM in the C library)
$GSL_ERANGE
Range error; used by mathematical functions when the result value is not representable because of overflow or underflow (like ERANGE in the C library)
$GSL_EFAULT
Invalid Pointer
$GSL_EINVAL
Invalid argument. This is used to indicate various kinds of problems with passing the wrong argument to a library function (like EINVAL in the C library).Invalid argument. This is used to indicate various kinds of problems with passing the wrong argument to a library function (like EINVAL in the C library).
$GSL_EFAILED
Generic Failure
$GSL_EFACTOR
Factorization Failed
$GSL_ESANITY
Sanity Check Failed
$GSL_ENOMEM
No memory available. The system cannot allocate more virtual memory because its capacity is full (like ENOMEM in the C library). This error is reported when a GSL routine encounters problems when trying to allocate memory with malloc.
$GSL_EBADFUNC
Problem with user-supplied function
$GSL_ERUNAWAY
Iterative process is our of control
$GSL_EMAXITER
Exceeded max number of iterations
$GSL_EZERODIV
Division by zero
$GSL_EBADTOL
Invalid user-specified tolerance
$GSL_ETOL
Failed to reach the specified tolerance
$GSL_EUNDRFLW
Underflow
$GSL_EOVRFLW
Overflow
$GSL_ELOSS
Loss of accuracy
$GSL_EROUND
Failed due to roundoff error
$GSL_EBADLEN
Matrix/vector lengths not compatible
$GSL_ENOTSQR
Not a square matrix
$GSL_ESING
Singularity Detected
$GSL_EDIVERGE
Integral/Series is divergent
$GSL_EUNSUP
Not supported by hardware
$GSL_EUNIMPL
Not implemented
$GSL_ECACHE
Cache limit exceeded
$GSL_ETABLE
Table limit exceeded
$GSL_ENOPROG
Iteration not converging
$GSL_ENOPROGJ
Jacobian not improving solution
$GSL_ETOLF
Cannot reach tolerance in F

Cannot reach tolerance in X

Cannot reach tolerance in Gradient

gsl_error
gsl_stream_printf
gsl_strerror($gsl_errno) - This function returns a pointer to a string describing the error code gsl_errno. For example, print ("error: gsl_strerror ($status)\n"); would print an error message like error: output range error for a status value of GSL_ERANGE.
gsl_set_error_handler
gsl_set_error_handler_off() - This function turns off the error handler by defining an error handler which does nothing. This will cause the program to continue after any error, so the return values from any library routines must be checked. This is the recommended behavior for production programs. The previous handler is returned (so that you can restore it later).
