[問題] 如何在編譯期建表
小弟需要在編譯期建一張很大的表，需求大概像這樣子，
簡化起見，假設長度 N，式子為 Exponential value of (index * alpha)
我希望達到這樣的效果：
static const double alpha = 3.0;
static const double Table[N] = {
exp(0*alpha),
exp(1*alpha),
exp(2*alpha),
...
exp(i*alpha),
...
exp((N-1)*alpha)
};
我希望一開始就把這個結果 load 到記憶體，就像手動宣告以上程式碼這樣。
而不可以做成
static Table[N];
Table[0] = exp(0*alpha);
Table[1] = exp(1*alpha);
...
Table[N-1] = exp((N-1)*alpha);
目前沒想到什麼好方法，主要是宣告 array 這塊，還要保證記憶體連續，還有實際上的
式子遠比 exp 複雜也希望不要使用數學展開成遞迴。
請問有人有好方法嗎？
感謝!
