plhs is an array whose length is nlhs, where your function must set pointers for the output mxArrays. Note It is possible to return an output value even if nlhs = 0, which corresponds to returning the result in the ans variable. To experiment with passing input arguments, build the mex...

要为具有不同含义的函数提供相同的名称 (例如, LENGTH , VALUE , MAX) ,并使用一致的自变量作为内置标量或聚集函数,请为动态 SQL 语句带来麻烦,或者在静态 SQL 应用程序重新绑定时; 应用程序可能失败,或者可能更糟糕的是,可能在提供不同结果的同时成功运行。 (parameter-declaration,...) 标识函数的输入参数个...
D5→ is thelookup_arrayargument. 0→ is the[match_type]argument. Output→#N/A. ISNA(MATCH(“*C?bleskill*”,D5,0))→ becomesISNA(#N/A). Output→TRUE. In theIFfunction, ISNA(MATCH(“*C?bleskill*”,D5,0))→ is thelogical_testargument. ...
