Can you please provide more details? What is the size of your input data,
how do you execute the code, what are the input parameters, etc.?

I cannot resolve potential issues if I cannot reproduce them.

470 cur_P[m] = exp(-beta * distances[m + 1] * distances[m + 1]);

The reason is sizeof(distance) = 24, but K = 150, how it works??

请问最后你是如何解决的
