采纳的回答： Arif Hoq

I want to convert decimal into binary .

Since my data is in string like

a = '56515219790691171413109057904011688695424810155802929973526481321309856242040'

I have tried dec2bin(a), but it gives output in different rows,

I need the following output

dec2bin(56515219790691171413109057904011688695424810155802929973526481321309856242040)

ans='111110011110010011110110001100010001101000000110101000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000'

But I'm not getting the same output by dec2bin(a).

Furthermore, I have to convert all the rows in to binary by importing a .txt file. Any help is much appreciated.

Thanking in anticipation.

This code contains many superfluous steps.

Note that SPLIT does not split any text, it just places the character vector in a scalar cell:

a = '56515219790691171413109057904011688695424810155802929973526481321309856242040';
c = split(a,' ')
c = 1×1 cell array
    {'56515219790691171413109057904011688695424810155802929973526481321309856242040'}

after that the CELL2MAT simply returns exactly the same character vector:

a1 = cell2mat(c)
a1 = '56515219790691171413109057904011688695424810155802929973526481321309856242040'
isequal(a,a1)
ans = logical
   1

So there is no point in any of that code, it literally does nothing.

The entire answer can be replaced by this much simpler code, which gives exactly the same output:

out = dec2bin(str2double(a))
out = '111110011110010011110110001100010001101000000110101000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000'

stephen, you are right. i was in a hurry while coding. i just checked the result not the coding size. Thank you very much for the hints.
