How can I turn initial value of chaos system to key for encryption algorithm?

I used chaos system for encryption with `(1.00001,3.26,22)` as initial value. I want to use these numbers as key for encryption algorithm.

- Should I turn my number to `(0100001 0326000 2200000)` (normalizing) and turn them to binary? or turn them separately to binary`(1.00001)(3.26)(22)`?

- Is there any function in matlab to convert double to binary like (str2bin)?

Actually i want to Specify how many bits are required for the key?

the first questions are unclear, but dec2bin is what you want for third. Please keep one question per question.

dec2bin is not working for double (dec2bin(2.3)=10)

[ES]

input of dec2bin must be a non-negative integer. if float to binary conversion is your problem, then write a logic to do the conversion.

However, for chaos generated encryption, logically should support ral x and not just binary x.

that is Xn+1=P*Xn*(1-Xn-1) and all X belong to the Real World.

All of Bifurcation Coefficient, Chaos Input, Chaos Output belong to the Real World if I am right.

Your posted question involves strings, not binary values.

There are multiple competing "standards" on converting double to binary. You need to define the representation you are looking for.

[Walter Roberson]

dec2bin(round(S * 10000))

but what do you want to do if the number is negative?
