How to convert sometimes negative decimal matrix to two's complement

I have a matrix that is 667648x2, full of sometimes negative decimals that range between -1 and 1. How would I convert this matrix into some output of 16 bit two's complement binary numbers? Thank you.

Hi

You can use num2bin() function to do that. Here is an example. You can check out the functions here to change the parameters as required

x = [-0.1 0.02 -0.4; 7 9 -11]

x =

   -0.1000    0.0200   -0.4000
    7.0000    9.0000  -11.0000

q = quantizer([16,8])

q =


        DataMode = fixed
       RoundMode = floor
    OverflowMode = saturate
          Format = [16  8]
y = num2bin(q,x)

y =

  6×16 char array

    '1111111111100110'
    '0000011100000000'
    '0000000000000101'
    '0000100100000000'
    '1111111110011001'
    '1111010100000000'
