Can some1 please help me. I have been trying to run this codes but getting a :: Function Definition not permitted.
HERE IS THE CODE.
>> %**************************************************************
% Filename : analysisFB.m
% Author : Necs
% Date : Aug 2014
% 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;

>> I also tried removing the function as illustrated in the example above but still giving an error

You need to save the code to a file named analysisFB.m

In the file, before it, you can only have blank lines and comment lines. The ">>" should be deleted if it is in the file at the beginning.

You appear to be trying to use a script file, with a function embedded in it.
The error message tells the story. Scripts cannot include function definitions of this sort.
Solution: The function must be saved as a separate m-file.
