我在sim_func.h中定义了这四个函数


void viterbi_cont(double *input, double qi[][NUM_VCTRS], char *output,
double PM[2][NUM_STATES], int surv[NUM_REG][2][NUM_STATES],
char *bank, int num_bits, char cvect[2][NUM_STATES]);
void convEnc(char x, int state, char *y, int *newState, char crate, char mem,
int *g);
void gaussian_ch(double *x, double *y, double sigma, int num_sym);
double dith_quant( double x, double delta, double dith );



为什么还是会出现这些问题呢？望高手指正，谢谢!

[解决办法]
simulate.c文件中要include "sim_func.h"
[解决办法]

探讨

simulate.c文件中要include "sim_func.h"

[解决办法]
只看到声明，没看到定义

lz 知道 声明 和 定义的区别把？
