not enough input arguments

Function a=abc(R,G,B)
enc =[2,3,1,1;1,2,3,1;1,1,2,3;3,1,1,2];
enc_gf=gf(enc,8);
R_encrypted=enc_gf*R;
G_encrypted=enc_gf*G;
B_encrypted=enc_gf*B;

R_encrypte=R_encrypted.x;
G_encrypte=G_encrypted.x;
B_encrypte=B_encrypted.x;

a(:,:,1)=R_encrypte;
a(:,:,2)=G_encrypte;
a(:,:,3)=B_encrypte;

@Puneeth sb: this time I formatted your code for you, but in future please do this yourself by selecting the code and clicking the {} Code button that you will find above the textbox.

Hi Puneeth,

please format the code using the code button. I guess, line 6 is

B_encrypted=enc_gf*B;

which would mean, that you call your function abc with only two input arguments (R and G) and forgot to pass third argument (B).

Sir before it was working properly. Now how can I make function abc to take all three inputs

[Titus Edelhofer]

Hi,

the problem is not in the function but in the function calling abc. Somewhere you write

X = abc(R, G);

instead of

X = abc(R, G, B);

The easiest is to use the debugger:

dbstop if error

and when the code stops, you'll see the code that calls abc.
