totalmemoryusage

Class: FunctionApproximation.LUTSolution
Namespace: FunctionApproximation

Calculate total memory used by a lookup table approximation

Syntax

memory = totalmemoryusage(solution,units)


Description

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

solution — Solution to get memory of

FunctionApproximation.LUTSolution object

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

units — Units in which to display the total memory used

'bits' (default) | 'bytes' | 'GiB' | 'KiB' | 'MiB'

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

Data Types: char

Output Arguments

memory — total memory used by a lookup table approximation

scalar

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

Examples

Calculate the Total Memory Used by a Lookup Table Approximation

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.
