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.

try this code for your attachment.
Output=dec2bin(table2array(A))

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.
