Lookup Tables

In the Lookup Tables of the basic library of blocks you can perform approximation and interpolation of values with usage of one-dimensional, two-dimensional and n-dimensional tables. These blocks allow you to approximate functions using pre-calculated values.

1-D Lookup Table

Approximate one-dimensional function.

2-D Lookup Table

Two-dimensional approximation function.

Direct Lookup Table (n-D)

Indexing an n-dimensional table to obtain a scalar, vector, or two-dimensional matrix.

Interpolation Using Prelookup

Usage of precomputed index and fraction values to speed up the approximation of an N-dimensional function.

Lookup Table Dynamic

Approximation of a univariate function using a dynamic table.

Matrix Interpolation

Interpolation between matrices.

n-D Lookup Table

Approximate n-dimensional function.

Prelookup

Calculates the number and fraction of the interval to be interpolated.
