How are Running Three Function Simultaneously

Hi friends.....

i have three functions must by " Running Simultaneously "

the functions :

[after_encryption_redchaotic] = Encryption_chaotic(redChannel,Rk1);

[after_encryption_greenchaotic] = Encryption_chaotic(greenChannel,Gk2);

[after_encryption_bluechaotic] = Encryption_chaotic(blueChannel,Bk3);

I write this code ;

% calling encryption each Channel

parfor i = 1:3

if i == 1

[after_encryption_redchaotic] = Encryption_chaotic(redChannel,Rk1);

elseif i==2

[after_encryption_greenchaotic] = Encryption_chaotic(greenChannel,Gk2);

else

[after_encryption_bluechaotic] = Encryption_chaotic(blueChannel,Bk3);

end

end

but appear this error :

Undefined function or variable 'after_encryption_redchaotic'.

Error in secure_home_surveillance_system (line 45)

[after_encryption_redSBOX] = Encryption_SBOX(after_encryption_redchaotic,SBox);
