revert
Revert compressed Lookup Table blocks to original versions
Description
revert( reverts the
Lookup Table blocks compressed by the
compressionResult)FunctionApproximation.compressLookupTables function back to their
original state.
replace(
reverts the lookup tables at the indices specified by compressionResult, index)index.
Examples
Compress All Lookup Table Blocks in a System
This example shows how to compress all Lookup Table blocks in a system.
Open the model containing the lookup tables that you want to compress.
system = 'sldemo_fuelsys';
open_system(system)
Use the FunctionApproximation.compressLookupTables function to compress all of the lookup tables in the model. The output specifies all blocks that are modified and the memory savings for each.
compressionResult = FunctionApproximation.compressLookupTables(system)

Use the replace function to replace each Lookup Table block with a block containing the original and compressed version of the lookup table.
replace(compressionResult);
You can revert the lookup tables back to their original state using the revert function.
revert(compressionResult);
