>> M = [1,2,3;4,5,6;7,8,9];
>> C = {'aa','bb','cc';'dd','ee','ff';'gg','hh','ii'};
>> F = @(n,c) sprintf('%d - %s',n,c{:});
>> Z = arrayfun(F,M,C,'uni',0)
Z = 
    '1 - aa'    '2 - bb'    '3 - cc'
    '4 - dd'    '5 - ee'    '6 - ff'
    '7 - gg'    '8 - hh'    '9 - ii'

what is that double qoutes " "

it shows error in matlab

[madhan ravi]

Which version of matlab are you using? If not use string() instead of "".

[Elysi Cochin]

i'm using 2016a

string is also not recognized

says undefined function or variable

[madhan ravi]

strcat(sprintfc('%d',mtric),{'-'},cell_array)
