Lookup Tables

Lookup Table 블록(예: Cosine 및 Sine)

Lookup Tables 라이브러리의 블록을 사용하여 비선형성을 모델링합니다. Lookup Table 블록은 데이터 배열을 사용해 입력값을 출력값에 매핑하여 수학 함수를 근사합니다. N개 변수에서 함수를 근사하려면 n-D Lookup Table 블록을 사용하십시오.

블록

1-D Lookup Table	Approximate one-dimensional function
2-D Lookup Table	Approximate two-dimensional function
Direct Lookup Table (n-D)	Index into n-dimensional table to retrieve element, vector, or 2-D matrix
Interpolation Using Prelookup	Use precalculated index and fraction values to accelerate approximation of N-dimensional function
Lookup Table Dynamic	Approximate a one-dimensional function using dynamic table
Prelookup	Compute index and fraction for Interpolation Using Prelookup block
Sine, Cosine	Implement fixed-point sine or cosine wave using lookup table approach that exploits quarter wave symmetry
n-D Lookup Table	Approximate n-dimensional function
