I have an array of characters assigned to variable m20 in the format of
CGNU
AEOS
NRRA
I am supposed to have a printed output of 'CAN GER NOR USA' but I am getting 'CANGERNORUSA' with the following code
fprintf('Countries with at least 20 medals: %s \n',m20)
if I were to add 5.0 infront of the %s placeholder, my outputs just vanishes instead of printing.
How can I insert space after printing 3 characters?

Str = ['CGNU'; ...
'AEOS'
'NRRA'];
CStr = cellstr(Str.'); % Transposing is important
fprintf('Countries with at least 20 medals:');
fprintf(' %s', CStr{:}); % Or: fprintf(' %c%c%c', Str)
fprintf('\n')

You must have stripped out the spaces in m20 before printing. Either add spaces back into m20 before printing or change print statement to this:
fprintf('Countries with at least 20 medals: %3s %3s %3s %3s\n',m20(1:3), m20(4:6), ...
m20(7:9), m20(10:12));

@Linggeas Kisten — Please learn to use the [{}Code] button to format your code. That will help significantly.
I formatted it for you, but not in time for ‘Mark M’ to benefit from it.
m20 = ['CGNU'
'AEOS'
'NRRA'];
fprintf('Countries with at least 20 medals: ')
fprintf(1,'%c%c%c ', m20)
fprintf('\n')
Countries with at least 20 medals: CAN GER NOR USA
