How to write a matrix output with a string in Matlab

Question

I am new to Matlab and I am not sure how to search for what I am trying to achieve.

Say I have a matrix that looks like this:

x = [1;2;3];

How do I output something like:

First row = 1
Second row  = 2
Third row = 3

Many thanks!

Well, you can always use fprintf, but it will not count the row numbers in english :)

fprintf('row value %d\n', x)

row value 1
row value 2
row value 3

You can also add individual row text, if you insist:

% convert your x vector to a cell matrix
Cx = mat2cell(x, ones(size(x)));

% define individual row texts in a cell matrix
str = {'First  row'; 'Second row'; 'Third  row'};

% print both using cellfun
cellfun(@(s,v)fprintf('%s %d\n', s, v), str, Cx);

First  row 1
Second row 2
Third  row 3

Maybe %d instead of %f would be better in that case.

Okay thank you very much! Just wondering is it also possible to just pick one of the numbers? Let's say i just want the second number (2) and printout row value 2

@jonprasetyo Use normal vector indexing - fprintf('%d\n', x(2))
