clearAllMemoizedCaches

Clear caches for all MemoizedFunction objects

Syntax

clearAllMemoizedCaches

Description

clearAllMemoizedCaches clears caches for all MemoizedFunction objects.

Examples

Clear All Memoized Function Caches

Create two memoized functions, and call them several times.

mf1 = memoize(@sin);
mf2 = memoize(@cos);

a = [mf1(0) mf1(pi/2) mf1(pi)];
b = mf2(pi/2);

View the statistics for the memoized function objects.

mf1.stats.Cache

ans = struct with fields:
         Inputs: {{1×1 cell}  {1×1 cell}  {1×1 cell}}
        Nargout: [1 1 1]
        Outputs: {{1×1 cell}  {1×1 cell}  {1×1 cell}}
       HitCount: [0 0 0]
      TotalHits: 0
    TotalMisses: 3

mf2.stats.Cache

ans = struct with fields:
         Inputs: {{1×1 cell}}
        Nargout: 1
        Outputs: {{1×1 cell}}
       HitCount: 0
      TotalHits: 0
    TotalMisses: 1

Clear all memoized function caches, and view the statistics again.
