Converting a decimal matrix to binary in GA

Hi,

I have a big problem in a multivariable function for Genetic Algorithms, I can't convert my decimal matrix to binary correctly it contains a signed and fractional numbers between -3 ,3.I need to finish the secript in 2 days Help please.

xx=-3+6*rand(10,1);

Thank You.

typecast() the decimal matrix to 'uint64', and then use bitget() to fetch the individual bits.

Example,

format long g
Num = -sqrt(5)

Num = 
         -2.23606797749979

as64 = typecast(Num, 'uint64')

as64 = uint64
   13835589633109914792

%checks to be sure that we are working with the same number
num2hex(Num)

ans = 'c001e3779b97f4a8'

dec2hex(as64)

ans = 'C001E3779B97F4A8'

%checks passed.

%get the bits
bits = bitget(as64, 64:-1:1)

bits = 1×64

1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 0 0 0 1 1 0 1 1 1 0 1

Chances are quite high that this technically correct solution is useless to you.

I suggest that you post a small selection of numbers and the corresponding binary that you would like to see as a result.
