I have a cell array of 2xn with strings and I would like to merge the text of all rows on a per column base, effectively yielding a 1xn cell array. To illustrate I have something like this...

[{'A'} {'C'}; {'B'} {'D'}] 
ans = 2×2 cell array
    {'A'}    {'C'}
    {'B'}    {'D'}

... and would like something like this:

[{'AB'} {'CD'}]
ans = 1×2 cell array
    {'AB'}    {'CD'}

在 MATLAB Online 中打开

C = {'A','C'; 'B','D'}
C = 2×2 cell array
    {'A'}    {'C'}
    {'B'}    {'D'}
D = cellfun(@(c)join(c,''),num2cell(C,1))
D = 1×2 cell array
    {'AB'}    {'CD'}
D = cellfun(@(c)[c{:}],num2cell(C,1),'uni',0)
D = 1×2 cell array
    {'AB'}    {'CD'}
