hi, I have :
aa1=[aa(1) aa(2) aa(3) aa(4) ];
aaseq(i,k2)={aa1};
dlmwrite('d.txt',aaseq);
I got this error:
??? Error using ==> dlmwrite at 112 The input cell array cannot be converted to a matrix.
how solve this problem?
thanks in advance

Don't convert it to a cell array with the {}.

Thanks,
I used {} because aa1 is :
'acsd'
and I want to place 'acsd' in aaseq(1,1) for example and so on, then store it in file.
how get that

Not with dlmwrite/read.

Why note just save it to a matfile:
doc save
?

save(s,'x')

thanks
i visited these links,and follow your suggestion
dlmwrite('k.txt', aaseq, 'delimiter', '', 'precision', '%c ');
aaseq =
'?RKG' 'RCRE' '?RFI' '???Q' 'AGQI' 'RIEE' 'RCIN'
'??HG' 'RKC?' 'AMLG' 'RGHI' 'RCIN' 'RQDM' 'RGGA'
ok, i got file as
?RKGRCRE?RFI???QAGQIRIEERCINAFGNRGGARDLR
??HGRKC?AMLGRGHIRCINRQDMRGGA?RGH?FP?RQL?
but when use dlmread
??? Undefined function or method 'dlmwread' for input arguments of
type 'char'.

unfortunately, the dlmwrite ran in command window just , when i used the original file, the problem is still
?? Error using ==> dlmwrite at 112
The input cell array cannot be converted to a
matrix.

Remember that when you use that code, you need to explicitly add any commas you want between elements.
I do not recommend using dlmwrite for character data: I only devised the code to do it because someone said it couldn't be done at all and I was feeling contrary.
If you want to write a cell array of strings in delimited form, you should use code such as
fid = fopen('k.txt','wt');
fmt = [ repmat('%s,', 1, size(aaseq,2)-1), '%s\n' ];
fprintf(fid, fmt, aaseq{:});
fclose(fid)
If you want double-quotes to appear around every string field, then modify the fmt line to
fmt = [ repmat('"%s",', 1, size(aaseq,2)-1), '"%s"\n' ];

i got file as I want when use what u suggested:
sdf,fgh
dfg,jkl
now, I want to read it
now i can read it by dlmread,right?
if so, why I got this error
??? Error using ==> dlmread at 145
Mismatch between file and format string.
Trouble reading number from file (row 1, field 1) ==> sdf,f
