Error using quantiz The codebook must be a real vector whose length is one more than the length of the partition. How to resolve this issue in the following code attached?

%Quantization
if quantization=='on '
 if psychoacoustic=='off'
 n=8;%default number of bits for each frame - sounds better but uses more bits
 end
 codebook = [min(C):(max(C)-min(C)/2^n):max(C)];
 partition = [min(C):((max(C)-min(C))/2^n):max(C)];
 [index,quant,distor] = quantiz(C,partition,codebook);
%find and correct offset
 offset=0;
 for j=1:1:N
 if C(j)==0
 offset=-quant(j);
 break;
 end
 end
 quant=quant+offset;
 C=quant;
 end

Unrecognized function or variable 'quantization'.

[Torsten]

codebook = [min(C):(max(C)-min(C))/2^n:max(C)];

instead of

codebook = [min(C):(max(C)-min(C)/2^n):max(C)];

[Anupama V]

The error remains the same.

[Torsten]

You choose codebook and partition to be equal.

And now read the error message.

Can you explain how?

[Torsten]

Yes, by adding one further element to "codebook".

Can you send the code snippet ..
