Israt - when I run your code, I observe the following result
>> cellfun( @(x) num2str(x, '%0.10g'), num2cell( [H',B'] ), 'UniformOutput', false)
ans =
'0' '0'
'10' '1'
'12' '1.1'
'15' '1.2'
which is a cell array of strings (where each string is converted from the numbers in your concatenated arrays). This seems very similar to your desired output. What are you expecting instead?
