Probably your code called the functions log() and exp() with

parameters that would cause for a value that can not be hold
in a double.
from math.h
typedef enum
{
DOMAIN = 1, /* argument domain error -- log (-1) */
SING, /* argument singularity -- pow (0,-2)) */
OVERFLOW, /* overflow range error -- exp (1000) */
UNDERFLOW, /* underflow range error -- exp (-1000) */
TLOSS, /* total loss of significance -- sin(10e70) */
PLOSS, /* partial loss of signif. -- not used */
STACKFAULT /* floating point unit stack overflow */
} _mexcep;
double _RTLENTRY _EXPFUNC log (double __x);
double _RTLENTRY _EXPFUNC exp (double __x);

Hi,

Thanks for ur reply,
I tried to catch the overflow exception but that doesnt prevent the
dialog box from appearing. I want to ignore these overflow exception and
continue with the execution of the code. Please can you help me how to
fix this problem.
thank you,
