how to conver double data type into signed binary in matlab?

I want to a certain data which is in double format converted into signed binary data type.

I'm providing the data in text file.

I want converted data also in single column matrix form

What is 'signed binary'. It isn't a data type so what do you actually want to convert your data to? do you mean you want to bin the data as 1, 0 or -1 depending on its sign?

I'm shocked that you actually asked what is "signed binary"

Signed mean first bit represent the sign & later its value.

Positive Signed binary numbers

The binary numbers having their MSB 0 are called “Positive signed binary numbers”.

Negative Signed binary numbers

The binary numbers having their MSB 1 are called “Negative signed binary numbers”.

You need to get off your high horse and reflect on the fact that your question is very badly worded.

The concept of signed binary numbers normally applies to integers only. Furthermore, as per my link, there are many ways to store the sign of a binary number, of which using the MSB is but one option. So Adam is correct to ask what is signed binary since you haven't told us which method to use.

Also, you certainly haven't explained how that apply to double numbers which are normally stored using IEEE 754 representation.

Perhaps, you should tell us what exact result you expect for 3.262e-37.

A = A = [-1.9, 1.7, -9, 12 13 -90 0]'
result = sign( A );

will give you -1, 0 or 1 depending on the sign of your data. Here A is just an example obviously. You would load your data in and use that instead.
