Arrays 如何在给定特定条件的情况下将元素传递到不同的单元格数组
我使用的是Arrays 如何在给定特定条件的情况下将元素传递到不同的单元格数组,arrays,matlab,string-matching,similarity,cell-array,Arrays,Matlab,String Matching,Similarity,Cell Array,我使用的是Matlab，我有两个不同的单元阵列，其中包含几个元素 主要的和次要的。虽然行数和顺序不相等，但两个单元格中都有一个共同的元素。我想要的是，每次验证一个条件时，从次要单元“传递”到主要单元的X个额外元素。条件是Y列（来自主单元格）和Z列（来自次单元格）匹配。例如： Primary cell array: ABC 970508 … FED 970524 … BAC 970601 … IGH 970606 … Secondary cell array IGH FINANCE B
MatlabPrimary cell array:
ABC 970508 …
FED 970524 …
BAC 970601 …
IGH 970606 …
Secondary cell array
IGH FINANCE BANK1
FED HEALTH PILLS
ABC FINANCE BANK3
What I would like to get in the ‘new’ primary cell array:
ABC 970508 FINANCE BANK3
FED 970524 HEALTH PILLS
BAC 970601 …
IGH 970606 FINANCE BANK1
有人能帮我吗？我相信，如果您使用数据库，您需要做的是内部连接。加入单元阵列将在中进行更全面的讨论，但将其应用到您的特定情况下，以下代码将为您提供所需的内容：
d1 = {'ABC' 970508
'FED' 970524
'BAC' 970601
'IGH' 970606};
d2 = {'IGH' 'FINANCE' 'BANK1'
'FED' 'HEALTH' 'PILLS'
'ABC' 'FINANCE' 'BANK3'};
%// get all possible keys, and convert them to indices starting at 1
[keys,~,ind] = unique( [d1(:,1);d2(:,1)] );
%// inner join
ind1 = ind(1:size(d1,1));
ind2 = ind(size(d1,1)+1:end);
loc1 = ismember(ind1, ind2);
loc2 = ismember(ind2, ind1);
innerJoin = cell(sum(loc1),3);
innerJoin(:,1) = d1(loc1,1);
innerJoin(:,2) = d1(loc1,2);
innerJoin(:,3) = d2(loc2,2);
innerJoin(:,4) = d2(loc2,3);
innerJoin =
'ABC' [970508] 'FINANCE' 'BANK1'
'FED' [970524] 'HEALTH' 'PILLS'
'IGH' [970606] 'FINANCE' 'BANK3'
MATLAB的最新版本似乎有一个表类型，它有一个本机的innerjoin函数，因此您可以使用这些函数而不是单元数组。看见但是，这不在我的MATLAB版本（2012a）中。您希望如何使用
