I have two char arrays a and b, say
a is a 5*14 char
var =
NKY 08/12/11 C
NKY 08/12/11 C
NKY 08/12/11 C
NKY 08/12/11 C
NKY 08/12/11 C
b is a 5*5 char
val =
5900
5905
5910
5915
5920
If I do strcat(a,b) or [a,b], it gives me
val =
NKY 08/12/11 C 5900
NKY 08/12/11 C 5905
NKY 08/12/11 C 5910
NKY 08/12/11 C 5915
NKY 08/12/11 C 5920
but I need
val =
NKY 08/12/11 C5900
NKY 08/12/11 C5905
NKY 08/12/11 C5910
NKY 08/12/11 C5915
NKY 08/12/11 C5920
Could anyone tell me how to do that? Very appreciated!

the problem is that your "5x5" char, the second input to strcat, is actually a 6x5 char, I believe. It has nothing to do with strcat - it's not adding the zero.

You either have trailing white space at the end of "a" or leading whitespace at the begining of "b". check out the following functions.
help strtrim
help deblank

The reason might be that you only showed a small portion of your data.
a=[5900:5:5920,15900];
b=num2str(a')
b =
5900
5905
5910
5915
5920
15900

strcat('NKY 08/12/11 C', strtrim(cellstr(b)))
Note that this allows you to skip the repmat of the constant string.
Note also that this will return a cell array of strings; you can use char() to convert back to a char array.
