Class: FunctionApproximation.LUTSolution
Package: FunctionApproximation

Calculate total memory used by a lookup table approximation


memory = totalmemoryusage(solution,units)


memory = totalmemoryusage(solution,units) returns the total memory used by the lookup table approximation specified by solution, in the units specified by units.

Input Arguments

expand all

Solution to get memory of, specified as a FunctionApproximation.LUTSolution object.

Units in which to display the total memory used, specified as a character vector.

Data Types: char

Output Arguments

expand all

Total memory used by a lookup table approximation, returned as a scalar.

Create a FunctionApproximation.Problem object defining a math function to approximate. Then, use the solve method to get a FunctionApproximation.LUTSolution object.

Calculate the total memory used by the FunctionApproximation.LUTSolution object using the totalmemoryusage method.
