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
