Description

The FunctionApproximation.LUTMemoryUsageCalculator class helps to calculate the memory used by each lookup table block, including 1-D Lookup Table, 2-D Lookup Table, and n-D Lookup Table, used in a model.

Construction

calculator = FunctionApproximation.LUTMemoryUsageCalculator() creates a FunctionApproximation.LUTMemoryUsageCalculator object. Use the lutmemoryusage method to calculate the memory used by each lookup table block in a model.

Use the FunctionApproximation.LUTMemoryUsageCalculator class to calculate the total memory used by lookup table blocks in a model.

Create a FunctionApproximation.LUTMemoryUsageCalculator object.

calculator = FunctionApproximation.LUTMemoryUsageCalculator

Use the lutmemoryusage method to get the memory used by each lookup table block in the sldemo_fuelsys model.

load_system('sldemo_fuelsys')
lutmemoryusage(calculator, 'sldemo_fuelsys')
ans =

  5×2 table
