Try this —

map = {'as','be','ce'};                         % Cell Array
a=[1 1 2 1 3 1 3 2];
b = map(a)

b = 1×8 cell array
    {'as'}    {'as'}    {'be'}    {'as'}    {'ce'}    {'as'}    {'ce'}    {'be'}

b = strtrim(sprintf(' %s ',b{:}))

b = 'as  as  be  as  ce  as  ce  be'

% To b=[as as be as ce as ce be].

map = ["as","be","ce"];                         % String Array
a=[1 1 2 1 3 1 3 2];
b = map(a)

b = 1×8 string array
    "as"    "as"    "be"    "as"    "ce"    "as"    "ce"    "be"

b = strtrim(sprintf(' %s ',b))

b = 'as  as  be  as  ce  as  ce  be'
