how can i print all the data from a computation in one line?

how can i do this? ex.

"for i=1:3

end"

desired output: i=[1 2 3] or i=123

..

ex.two

" x=input('input value of x: ') %then the user will enter x=[1:5]

y=x.*2;"

desired output: y=[2 4 6 8 10] or y=246810

..

ex three

N=35

while N>=2

        A=rem(N,2)
        N=floor(N/2)
end

and my desired output is A=11000 or A=[1 1 0 0 0]

how could i do this?

Answer 1

 ii=1:3

or

 ii=[1:3]

thats not what i meant, i just made a simple example because im going to use this code for a more complicated one.

Then what did you mean? Are you wanting to know how to use fprintf()?

[jelly]

like this..

N=35

while N>=2

        A=rem(N,2)

        N=floor(N/2)

end

and my desired output is A=11000 or A=[1 1 0 0 0]

[Image Analyst]

Like this:

>> N=35
N =
    35
>> nBinary = dec2bin(N)
nBinary =
100011
>> nBinaryReversed = nBinary(end:-1:1)
nBinaryReversed =
110001

ughhh, you just dont get me, haha, well any way, thanks for bothering to answer :).

[Thomas]

I guess this is what u need

N=35;
count=1;
while N>=2

        A(count)=rem(N,2);

        N=floor(N/2);
 count =count+1;
end  

 A

Hey tom, yes this is really what i need, finally someone get what i mean, HAHA, thankyou for spending time understanding my problem, thanks bro.

You will find that this code will not print the result on one line at some point around 2^19 to 2^24 (depending exactly how wide your command window is set to.) Instead you will get a display such as

A =

Columns 1 through 18

     0     0     0     0     0     0     0     0     0     0     0     0     0     0     0     0     0     0

Columns 19 through 20

     0     0

The output for A will also not have the [] that you required when there were spaces between the elements.

You can fix both of those problems by not displaying A and instead displaying

mat2str(A)

If you're going to allow the user to enter brackets and colons, then you're going to have to accept it as a string and either call eval(), or parse the string to extract out the individual numbers.

N=35
fprintf('%s', 'A=');
while N>=2

          A=rem(N,2);
          fprintf('%d', A);
          N=floor(N/2);
  end
  fprintf('\n')

Note that your logic will fail to print the last binary digit.
