How to align names with the numbers in a matrix?

2 views (last 30 days)
Hello!
I have to put heading row over the data matrix so I used the following code:
a=[12 13 14];
b={'a'; 'b'; 'c';};
c=[char(b)'; num2str(a)]
it gives me:
C= abc
12 13 14
But I want to align the first row over the second one.
required output:
C= a b c
12 13 14

Can't you use a table - using the entries in b as the VariableNames and a as the row data

This is what I am looking for.
I am confused about how to use it for my case @David Fletcher.
Name={'a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j' 'k' };
Data=[ 1 2 3 4 5 6 7 8 9 10 11
12 13 14 15 16 17 18 19 20 21 22
23 24 25 26 27 28 29 30 31 32 33];
Name is 1x11 array
Data is 3x11
I can assign variables as
a=Data(:,1)....
but thats a lengthy process and my matrix size can vary.
How can I use table function so that I have "Name" as heading row of table and "Data" matrix as its value.
Required output:
a b c d ......
__________ ______ ______ ______ ______
1 2 3 4 ......
12 13 14 15 ......
23 24 25 26 ......

So, finally I found what I was looking for
Name={'a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j' 'k' };
Data=[ 1 2 3 4 5 6 7 8 9 10 11; 12 13 14 15 16 17 18 19 20 21 22; 23 24 25 26 27 28 29 30 31 32 33];
T=struct2table(cell2struct(num2cell(Data,1),Name,2));
Thanks :)

a=[12 13 14];
b={'a'; 'b'; 'c';};
fprintf('%5s %5s %5s\n', b{:}); fprintf('%5d %5d %5d\n', a);
a b c 12 13 14

@Walter Roberson If I have huge data this method messes up and made the output hard to read :(.
Is there another method by which "a" and "b" can be included in same array or matrix?
