Ordering vectors of numbers of type double and strings according to another vector

조회 수: 1 (최근 30일)
How do I order the following arrays?
vector_1 = [1 3 7 8 9 10];
string_1 = {'apples' 'pears' 'plums' 'oranges' 'peaches' 'grapes'};
Specifically, I want to re-order them according to [3 1 7 9 8 10] for vector_1.

vector_1 = [1 3 7 8 9 10];
string_1 = {'apples' 'pears' 'plums' 'oranges' 'peaches' 'grapes'};
vector_1_reordered = [3 1 7 9 8 10];
[~,idx] = ismember(vector_1_reordered,vector_1);
string_1_reordered = string_1(idx)
string_1_reordered = 1×6 cell array
{'pears'} {'apples'} {'plums'} {'peaches'} {'oranges'} {'grapes'}

You could write a simple loop...
string_1 = {'apples' 'pears' 'plums' 'oranges' 'peaches' 'grapes'};
vector_1 = [1 3 7 8 9 10];
vector_2 = [3 1 7 9 8 10];
idx = [];
for ii = 1:numel(vector_1)
idx(ii) = find(vector_1 == vector_2(ii), 1);
end
string_2 = string_1(idx)
string_2 = 1×6 cell array
{'pears'} {'apples'} {'plums'} {'peaches'} {'oranges'} {'grapes'}
