stats
Return cached values and statistics for MemoizedFunction
object
Syntax
Description
Examples
Create a MemoizedFunction
object by memoizing the plus
function.
mf = memoize(@plus)
mf = MemoizedFunction with properties: Function: @plus Enabled: 1 CacheSize: 10
Call the memoized function several times. The first time you call the function with a particular set of inputs, MATLAB® caches the results.
a = mf(13,42); % calls plus; caches results b = mf(7,33); % calls plus; caches results c = mf(13,42); % does not call plus; returns cached results d = mf(5,120); % calls plus; caches results e = mf(13,42); % does not call plus; returns cached results f = mf(7,33); % does not call plus; returns cached results
Call the stats
function.
s = stats(mf)
s = struct with fields:
Cache: [1×1 struct]
MostHitCachedInput: [1×1 struct]
CacheHitRatePercent: 50
CacheOccupancyPercent: 30
Determine which sets of inputs you used the most.
s.MostHitCachedInput
ans = struct with fields:
Hits: 2
Input: {[13] [42]}
Obtain the cached results.
c = s.Cache
c = struct with fields:
Inputs: {{1×2 cell} {1×2 cell} {1×2 cell}}
Nargout: [1 1 1]
Outputs: {{1×1 cell} {1×1 cell} {1×1 cell}}
HitCount: [2 1 0]
TotalHits: 3
TotalMisses: 3
Display all sets of cached inputs and outputs alongside how many times MATLAB accessed the cached values.
T = cell2table([c.Inputs' c.Outputs'],'VariableNames',{'Inputs','Outputs'}); T.Times_Cache_Accessed = c.HitCount'
T=3×3 table
Inputs Outputs Times_Cache_Accessed

Input Arguments
Function with memoization semantics, specified as a
MemoizedFunction
object.
Output Arguments
MemoizedFunction
statistics, returned as a structure
containing these fields.
Field | Description |
---|---|
| Cached results, returned as a structure. If

| Inputs for the most accessed cached values, returned as a structure. The structure contains the following fields:
|
| Percentage of times an input was found in the
cache, returned as a double. This property is computed
by
|
| How full the cache is, returned as a double
representing a percentage. This property is computed by
