概要

プロトタイプ宣言	動作説明
std::vector sinWave(double freq2generate, double freq2sample, uint len);	sin 波を生成する
std::vector cosWave(double freq2generate, double freq2sample, uint len);	cos 波を生成する

使用例

#include <sstd/sstd.hpp>

int main(){
    double freq2generate = 3; // Hz
    double freq2sample = 10;  // Hz
    uint len=10;              // 10 Hz 10 sample = 1 sec
    std::vector<double> sin_wave = sstd::sinWave(freq2generate, freq2sample, len);
    std::vector<double> cos_wave = sstd::cosWave(freq2generate, freq2sample, len);

    sstd::printn(sin_wave);
    sstd::printn(cos_wave);
}
