problem with dlmwrite

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

Answer 1

[Sean de Wolski]

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

[Sean de Wolski]

Not with dlmwrite/read.

[Sean de Wolski]

Why note just save it to a matfile:

doc save

?

[huda nawaf]

i did

s='m.mat'

for ex. x={'gh' 'kl'};

save(s,'x')

but when click on m.mat file did not opened

dlmwrite() cannot write cell arrays, and is very limited in writing text. Please see

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.

[Walter Roberson]

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
