Thread Subject: concatinating strings--error

Hello,

Please help me figure this out:

vb=[-13,67,-227,598,-1353,2839,-6242,24537,16172,-5275,2469,-1171,508,-187,52,-9;];
 
  coe=dec2hex(bin2dec(dec2bin(mod((vb),2^16),16)));
%coe is the two's complement of each elements of vb. It is 16*4 char
for k=1:15
    coef(k)=[coe(k,1),coe(k,2),coe(k,3),coe(k,4)];
end
% Coef is an 16*1 array.

This is giving the error==>??? Subscripted assignment dimension mismatch.

Thanks

Is this a homework assignment?

Yes, written that way you're selecting four separate characters and
trying to assign them to one array location. That would need it to be
written as

coef(k,:)=[coe(k,1),coe(k,2),coe(k,3),coe(k,4)];

It would be simpler to write

coef(k,:)=coe(k,:);

but that is the same in the end as

coef=coe;

Thanks for the answer, but this is not what I am looking for.
for example when vb=-13, coe(1,1)=F,coe(1,2)=Fcoe(1,3)=F and coe(1,4)=3
when vb =67 coe(2,:0)=0043.
I want coef(1,1)=FFF3 (Thatis coef(1,1)=coe(1,:) and
coef(2,1)=coe(2,:).... so on and
coef(16,1)=coe(16,:)

As a string?

If so, you need cellstr()--

 >> coef=cellstr(coe);
 >> coef{1}
ans =
FFF3
 >> whos coef
   Name Size Bytes Class

   coef 16x1 1600 cell array

Grand total is 80 elements using 1600 bytes

 >>

NB the need to dereference the cell contents w/ the curly braces instead
of parens above

Thanks for your help.
