=SUMPRODUCT((K2:K13"")/COUNTIF(K2:K13,K2:K13&"")) 如(K2:K13"")是什么意思,COUNTIF(K2:K13,K2:K13&"")这个又是什么意思,为啥不是COUNTIF(K2:K13,K2:K13)?

=SUMPRODUCT((K2:K13)/COUNTIF(K2:K13,K2:K13&)) 如(K2:K13)是什么意思,COUNTIF(K2:K13,K2:K13&)这个又是什么意思,为啥不是COUNTIF(K2:K13,K2:K13)? MATLAB矩阵相加K1=[k11 k12 k13;k21 k22 k23;k31 k32 k33]K2=[k11 k13 k14;k31 k33 k34;k41 k43 k44]K1 K2中对应的元素各不相同我现在想把其中下标相同的加在一起扩充为4*4的矩阵,应该怎么实现?也就是说k11 k12 k13k21 k =sumproduct(sheet1!c2:c1000=重庆)*(sheet1!k2:K2:k1000=已买）*(sheet1!h2:h1000=重庆!a3)) a3日期 请求简单化以下公式!=(K5+K9+K13+K17+K21+K25+K29+K33+K37+K41+K45+K49+K53+K57+K61+K65+K69)/(H5+H9+H13+H17+H21+H25+H29+H33+H37+H41+H45+H49+H53+H57+H61+H65+H69)=1-(L5+L9+L13+L17+L21+L25+L29+L33+L37+L41+L45+L49+L53+L57+L61+L65+L69+K5+K9+K13+K17+K2 =SUMPRODUCT怎么应用 =SUMPRODUCT((A1:A8 sumproduct函数 =sumproduct((mod(a2:a13,7) 2k13中的Intense 这是我计算加权平均分的公式=SUMPRODUCT(C2:K2,{3,4,3,3,2,3,2,2,3})/SUM(3,4,3,3,2,3,2,2,3) 但是不能剔除小于60分的,C2:K2是分数,怎样能让小于60的不计算进去excel =SUMPRODUCT(--(C3:G3=H3))是什么意思 excel公式SUMPRODUCT(--(A1:A4= =SUMPRODUCT(($A$1:$A$6 .=SUMPRODUCT((TEXT(A1:A400,D) .=SUMPRODUCT((TEXT(A1:A400,D) 关于sumproduct函数解释=SUMPRODUCT(N(LEN(A1:A10)>4)) EXCEL有谁懂?=SUMPRODUCT(LEFT(G$7:AK$7,2)*G8:AK8)/SUMPRODUCT(G8:AK8) -1=k1+k2 5=3k1+k2/3 1=-e^-k2+e^-k1;求k2-k1
