Lookup Tables

Lookup table blocks such as Cosine and Sine

Use blocks from the Lookup Tables library to model nonlinearity. Lookup table blocks use arrays of data to map input values to output values, approximating mathematical functions. To approximate a function in N variables, use the n-D Lookup Table block:

Blocs

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