CSimpleMap::SetAt Sets the value associated with the given key. BOOL SetAt(const TKey& key, const TVal& val); Parameters key The key. val The new value to assign. Return Value Returns TRUE if the key was found, and the value was successfully changed, FALSE otherwise. ...
Then set the scope to InputOutput in the Port Specification table and assign the resulting function output to the input variable in the custom function. You can map a global variable from your custom code into Simulink using Automatically infer global variables as function interfaces parameter from...

以347 Top K Frequent Elements 为例,给定一个数组,求数组里出现频率最高的 K 个数字,比如对于数组 [1,1,1,2,2,3],K=2 时,返回 [1,2]。解决该问题的思路比较常规,首先用 hashmap 记录每个数字的出现频率,然后可以用 heap 来求出现频率最高的 k 个数字。
Under some circumstances, aPC doesnot map to a known function. In such cases, the PC is mapped to the special function named<Unknown>. The following circumstances show PCs mapping to<Unknown>: When a function written in C or C++ is dynamically generated, and information about the function is...
