seperation columns when one string in number other is txt.

names=['john'; 'ravi'; 'mary'; 'xiao']

howdy=char('10', '20', '30')

result=[howdy(2,:) names(3,:)]

result=20mary

I wanna create "20 marry" with spaces between columns, how can I add the spaces between the columns?

result=[howdy(2,:), ' ', names(3,:)];

or use sprintf(), like I prefer:

result = sprintf('%s %s', howdy(2,:), names(3,:));

By the way, if any names are not exactly the same length as the others, then you'll have to have names be a cell array, not a character array and you'll have to use braces, not parentheses, like I did here.

but when I try to result=[howdy(:,1), ' ', a(:,1)] horzcat error occurs how can I fix this error?

or result=[howdy, ' ', a]

[sermet]

a=names

Well you switched from rows like you started (and I answered) to columns. Look - the indexes inside howdy and a went from the first index being specified to the second index being specified. So now you're trying to stitch together horizontally vertical columns that have different heights. You can't do that because the matrix would no longer be rectangular - it would have an irregular bottom edge.
