clearAllMemoizedCaches
清除所有 MemoizedFunction
对象的缓存
说明
clearAllMemoizedCaches
可清除所有 MemoizedFunction
对象的缓存。
示例
清除所有储存函数缓存
创建两个储存函数,并多次调用它们。
mf1 = memoize(@sin); mf2 = memoize(@cos); a = [mf1(0) mf1(pi/2) mf1(pi)]; b = mf2(pi/2);
查看储存函数对象的统计信息。
mf1.stats.Cache
ans = struct with fields:
Inputs: {{1x1 cell} {1x1 cell} {1x1 cell}}
Nargout: [1 1 1]
Outputs: {{1x1 cell} {1x1 cell} {1x1 cell}}
HitCount: [0 0 0]
TotalHits: 0
TotalMisses: 3
mf2.stats.Cache
ans = struct with fields:
Inputs: {{1x1 cell}}
Nargout: 1
Outputs: {{1x1 cell}}
HitCount: 0
TotalHits: 0
TotalMisses: 1
清除所有储存函数缓存,并再次查看统计信息。

ans = struct with fields:
Inputs: {}
Nargout: []
Outputs: {}
HitCount: []
