This script in the MathScript node would look like: t = 0:0.1:2*pi;plot(t, sin(t), t, cos(t)); To convert this into MATLAB function and call it from LabVIEW: Create a .m file (say customPlot.m) and Create a function matching the name of the file, and copy the contents ...
public static (float Sin, float Cos) SinCos (float x); 參數 x Single 以弧度為單位的角度。 傳回 ValueTuple<Single,Single> 的正弦和余弦 x。 如果 x 等於NaN、NegativeInfinity 或PositiveInfinity,則這個方法會傳回 NaN。 備註 角度x 必須是弧度。 乘以 Math.PI /180 將度轉換為弧度。 此方法會...

正交:\int_{0}^{2\pi}sin\ x\cdot cos\ x dx=0 因此sin和cos组成的复杂信号可以表示为如下公式,这就是傅里叶级数(三角函数形式): 经过定积分推导可知,sin和cos常见的正交关系: sin和sin在相同频率下不正交:\int_{0}^{2\pi}sin\ nx\cdot sin\ nx dx=\pi ...
