using the following "function output = conv_enco(input, K, g)" i have to call "function [next_state, output] = conv_enc(crt_state, input, K, g)" how can it be done in a matlab code? Kindly let me know.

How can call the above first function1 using function2 in a matlab code?

[Walter Roberson]

function output = conv_enco(input, K, g)
  crt_state = randi(1234);
  [next_state, output] = conv_enc(crt_state, input, K, g);
end

It is advised that you do not name a variable "input" as doing that interferes with the MATLAB input() routine.

i have my input sequence as [1 0 1 0 1 0].input is the variable which was mentioned in my question.I cannot avoid it

[Walter Roberson]

You are writing the code. Name the variable something else. For example,

function output = conv_enco(input_sequence, K, g)
  crt_state = randi(1234);
  [next_state, output] = conv_enc(crt_state, input_sequence, K, g);
end

i am new to matlab and calling functions in matlab.

[Walter Roberson]

If you want conv_enco to be called by conv_enc then you can code

function [next_state, output] = conv_enc(crt_state, input_sequence, K, g);
  fprintf('ignoring unneeded crt_state that was:\n');
  disp(crt_state);
  output = conv_enco(input_sequence, K, g);
  next_state = 7;  %lucky 7
end
