Numeros complexos em C e o método de newton


Recommended Posts

Em C++ até penso que há a bblioteca "complex", mas nunca usei (pelo nome, penso que se refere a numeros complexos).

So mais um problema...

a minha lib math.h parece nao estar a funcionar bem....

um simples programa de teste:


int i,f;
double x=2;
printf("\n\n\n\n\n%d\n\n%d\n\n", i,f);

resulta em:

/tmp/cc4qYHyB.o: In function `main':
power.c:(.text+0x28): undefined reference to `log'
collect2: ld returned 1 exit status

e isto tanto com log como sin, cos etc... :S
