Can some1 please help me. I have been trying to run this codes but getting a :: Function Definition not permitted.
HERE IS THE CODE.

% Purpose : Reconstruct the image using 2D forward discrete wavelet transform %**************************************************************
function wc = analysisFB(data,lpfilter,hpfilter)
[n_row,n_col] = size(data);
n = n_row;
le = length(lpfilter);
%###################### operation on the rows ##############################
pad_data = [data data(:,1:le)];
lpcoeff = downsampleConv(pad_data,lpfilter,le,n);
hpcoeff = downsampleConv(pad_data,hpfilter,le,n);
%transpose the matrix
data = [lpcoeff hpcoeff]';
%###################### operation on thecolumns###########################
pad_data = [data data(:,1:le)];
lpcoeff = downsampleConv(pad_data,lpfilter,le,n);
hpcoeff = downsampleConv(pad_data,hpfilter,le,n);
%transpose the matrix again
wc = [lpcoeff,hpcoeff]';
return;
%local function
function downsample_coeff = downsampleConv(coeff,filter,le,n)
downsample_coeff = conv2(coeff,filter);
downsample_coeff = downsample_coeff(:, le:2:(le+n -1));
return;
??? Undefined function or variable 'data'.
