displaying system format?

could I display system as

 x*[25
  64
 144]+y*
   [5
   5
  12]+z*[
   1
   1
   1]=[
   289
   345
   123]

but the vectors are vertical

The closest the symbolic toolbox can do is

>> x*[25;64;144] + y*[5;5;12] + z*[1;1;1] == [289;345;123]
ans =
   25*x + 5*y + z == 289
   64*x + 5*y + z == 345
 144*x + 12*y + z == 123
>> pretty(ans)
/  25 x + 5 y + z == 289  \
|                         |
|  64 x + 5 y + z == 345  |
|                         |
\ 144 x + 12 y + z == 123 /

It is not possible at the MATLAB level to prevent the multiplications from taking place (it is possible if you are working in a MuPad notebook.)

To get the output you are looking for, you will need to do the output formatting yourself.

yes, I tried to make it in specific format but a lot of errors appear I used "display" function ,and nothing came true.

errors because I am interacting with the vectors as 'sym' and display in the only function for displaying this datatype ,and it does not accept multiple input at a time.

xm = [25;64;144];
ym = [5;5;12];
zm = [1;1;1];
rm = [289;345;123];
fprintf('x * [%5g; + y * [%5g; + z * [%5g; = [%5g;\n', xm(1), ym(1), zm(1), rm(1));
temp = [xm(2:end-1), ym(2:end-1), zm(2:end-1), rm(2:end-1)];
fprintf('     %5g;        %5g;        %5g;    %5g;\n', temp.' );  %transpose is important
fprintf('     %5g]        %5g]        %5g]    %5g]\n', xm(end), ym(end), zm(end), rm(end));

why i am getting this result when i run the previous code I mean the division not decimal as your code

if true
  % code
25*x + 5*y + z == 534/5
  64*x + 8*y + z == 886/5
144*x + 12*y + z == 1396/5
end
