how to insert space between strings using strcat?

[Jane]

Hi,
I tried to use strcat to concatenate different strings, but seems
that strcat ignore blank strings. For example,
strcat('A','B') is the same as strcat('A',' ','B'). Does anybody
know how to create the space between different strings?

Thanks,
Jane

strcat chomps trailing spaces in strings. You might want to just use
matrix concatenation (horzcat):
['A', ' ', 'B']

otherwise, try sprintf for more flexibility

or enclose the string in {} which will tell strcat to respect spaces.

strcat({'hello '},{'Anna','Jane','Mark'});
or
strcat('hello',{' '},{'Anna','Jane','Mark'});


will give you what you want.

Yes, this is the documented behavior of STRCAT.

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/strcat.html

As stated in the third line of the Description section of that page, as well
as Richard and Michael's posts, use the cell array syntax or use plain old
concatenation with [].

Thank you very much. It helped me a lot.

From the strcat documentation:

Trailing spaces in character array inputs are ignored and do not appear
in the output. This is not true for inputs that are cell arrays of
strings. Use the concatenation syntax [s1 s2 s3 ...] to preserve
trailing spaces.
