Hello sir,
i m doing one program shows some error.
can u help me?

Ie=imread('imd.jpg');
[x,y]=size(Ie);
h=x/2;
for i=1:x
    for j=1:y
    if Ie(i,j)==0
       Ic(i,j)=0;
    else if ((Ie(i+1,j-1)==1)& (Ie(i+1,j+1)==1))
              Ic(i,j)=0;
    else if (((Ie(i+1,j-1)==1)&(i<=h))|(Ie(i+1,j+1)==1) & (i>h))
        Ic(i,j)=1;
    else if (((Ie(i+1,j+1)==1) & i<=h)|| (Ie(i+1,j-1)==1)& (i>h))
            Ic(i,j)=-1;
                end %if
                end %for
        end

And how are we to know what error that might be if you provide no clues...

There's no such thing as the 0th column of a matrix in MATLAB. The first
row/column/element/etc. of an array is row/column/element/etc. 1.

  I see at least two problems here.  First, in the for-loops the index j-1 can equal zero and the indices i+1 and j+1 can be above the range of Ic which will produce an error message.  Second, the 'elseif' should not have a space between the 'else' and the 'if'.  As it stands it does not have enough end's and that will create a parsing error message when the program is compiled.
