I want to convert the following:
mat = [1 2 3; 4 5 6 ; 7 8 9];
into the following array of strings,
arr = {'1,2(3)', '4,5(6)', '7,8(9)'};
How can I do that?

Ran in:
Since R2016b:
mat = [1,2,3; 4,5,6; 7,8,9];
compose('%u,%u(%u)',mat)
ans = 3x1 cell array
{'1,2(3)'} {'4,5(6)'} {'7,8(9)'}

You could use sprintf.
mat = [1 2 3; 4 5 6 ; 7 8 9];
arr = cell(1, size(mat, 1));
for k = 1:numel(arr)
arr{k} = sprintf('%d,%d(%d)', mat(k,:));
end
arr =
'1,2(3)' '4,5(6)' '7,8(9)'

mat = [1 2 3; 4 5 6 ; 7 8 9];
arr = {'1,2(3)', '4,5(6)', '7,8(9)'};
nx = size(mat,1) ;
iwant = strcat(num2str(mat(:,1)),',',num2str(mat(:,2)),repelem('(',nx,1),num2str(mat(:,3)),repelem(')',nx,1))
