Let's say that i have
data =
1×4 cell array
{12×1 cell} {12×1 cell} {12×1 int32} {12×1 int32}
first 12x1 cell array contains Names, second sournames, third age and forth id numer.
I would like to do something like extract just 1st elements from each cell array - it woul'd give me an array of data for one person, then do it for the next 11 rows.
How to make it? It should be convert into struct, and I know that repmat function can be useful here, but i have no clue how to do it.

You can convert cell to structure or table using cell2struct and cell2table. Read about them and then it should be easy to follow.

It would help you to learn about tables, which are more appropriate in this case than cell arrays:
% Original cell array:
data = {{'Smith' ; 'Gold'}, {'Ann' ; "Agnes"}, {'22' ; '24'}, {'1' ; '2'}}
% Convert cell array into table:
t = table(data{1}, data{2}, data{3}, data{4}, ...
'VariableNames', {'LastName', 'FirstName', 'Age', 'IDNumber'})
% Get out row 1:
a = t(1, :)
% Get out row 2:
b = t(2, :)

T = cell2table(C,...
'VariableNames',{'Name' 'SirName' 'Age' 'Id'}) ;
T
You have the data in Table T, you can extract what you want.
