運(yùn)算練習(xí)題，已知有一數(shù)組Arr1[Num1，Num2，Num3]，求它們分別乘以另一數(shù)組Arr2[Num4,Num5]得到數(shù)組Arr3[Num6,Num7,Num8,Num9,Num10,Num11]，再求數(shù)組SumArr3的總和等于多少？求大佬使用ST結(jié)構(gòu)文本循環(huán)語(yǔ)句完成告知思路和標(biāo)簽定義，題目的意思相當(dāng)于：Num1*Num4+Num2*Num4+Num3*Num4+Num1*Num5+Num2*Num5+Num3*Num5 = SumArr?

IF M800=1 THEN;
rr:=0;
ee:=0;
o:=0;
FOR rr := 0 TO 3 DO
    FOR ee :=0 TO 2 DO
        Arr3[o]:=    Arr1[rr]*Arr2[ee];
        o:=o+1;
      END_FOR;
END_FOR;
END_IF;
