비선형성

룩업 테이블로 비선형성 모델링, 입력값을 출력값에 매핑하여 수학 함수 근사

비선형성 모델링에 익숙하지 않은 경우 먼저 Lookup Table 블록을 사용해 보십시오. 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
n-D Lookup Table	Approximate n-dimensional function
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
