How do you order the results of the combination?

I changed 14 letters to cell type first.

Then, using a combination (C) of 14 cell types, we got 364 results. (14C3)

EX> abc

abd

abe....

I want to match each of the 364 results and each of the 364 date

(01-01 abc

01-02 abd

01-03 abe.....)

So I thought I had to order 364 results first.

But I don't know what to do.

And maybe my way was wrong.

Give them a hand.

I am a foreigner and I have no friend who uses Matlab among my friends.

Like this?

% Create 1-by-14 cell array {'a','b', ..., 'n'}
str = 'a':'n';
c = split(str,'')';
c([1 end]) = [];

% Create all the 3-character selection
cmb = nchoosek(c,3);
cmb = strcat(cmb(:,1),cmb(:,2),cmb(:,3));

% Create 364 date and 3-character lookup table
date = datetime(2019,1,1:364)';
T = table(date,cmb,'VariableNames',{'date','char'});

The result is as follows:

>> T

T =

364×2 table

date char

__________ _______

2019/01/01 {'abc'}

2019/01/02 {'abd'}

2019/01/03 {'abe'}

....

2019/12/30 {'lmn'}
