Hello community,

I want to accomplish the following with my code:

Originally I don't know the number of names in array A and I have to group them in just one cell concatenating them with the delimiter "/". I tried the for loop with no success and it is not necessary at all. Any hints on how I can accomplish this? I appreciate all the help.

As well as JOIN() as Chunru showed here are a few other approaches:

A = {'ABC','DEF','HIJK'};
B = char(join(A,'/'))
B = 'ABC/DEF/HIJK'
C = sprintf('/%s',A{:});
C = C(2:end)
C = 'ABC/DEF/HIJK'
D = cell2mat(strcat('/',A));
D(1) = []
D = 'ABC/DEF/HIJK'
A(2,1:end-1) = {'/'};
E = [A{:}]
E = 'ABC/DEF/HIJK'

% using cell array of char
A = {'ABC', 'DEF', 'HIJK'}
A = 1×3 cell array
    {'ABC'}    {'DEF'}    {'HIJK'}
B = join(A, '/')
B = 1×1 cell array
    {'ABC/DEF/HIJK'}
% using  string
C = string(A)
C = 1×3 string array
    "ABC"    "DEF"    "HIJK"
C = join(C, '/')
C = "ABC/DEF/HIJK"
