convert integer double code huffman

Hello, can any one help me to with a malab code that help me to find a huffman code and a command or function to convert integer to double then double to integer and thanks

   DoubleValue = double(IntegerValue);

   IntegerValue = uint8(DoubleValue);

thank you mr Walter Roberson but my problem is in code huffman

X1=blkproc(e,[8 8],'zigzag(a)'); 

[M1 M2]=size(X1); 

taille3=M1*M2;

XZvaH3=reshape(X1',1,taille3); 

   XZvaH3=uint8(XZvaH3);

[XuV,XfuV]=proba(XZvaH3);

   somfuV=sum(XfuV); 

   XfrequV=XfuV./somfuV;

   [dict1,avglen]= huffmandict(XuV,XfrequV);

   codeV= huffmanenco(XZvaH3,dict1);

XZvHR = huffmandeco(codeV,dict1);

   X2R=vec2mat(XZvHR,M2);

    R=8;

   uR=blkproc(X2R,[1 R^2],'zigzaginv(x)');

the error is in the huffman encoding for input values of type double and when I convert unit8 when decoding I do not get the original image and thanks

What is proba? Is it http://www.mathworks.com/matlabcentral/fileexchange/31776-image-compression-based-on-dct/content/proba.m ?

What are class(XfuV) and class(somfuV) ?
