(Image Enhancement)

function [final]=fftenhance(image,f)
I = 255-double(image);
[w,h] = size(I);
%out = I;
w1=floor(w/32)*32;
h1=floor(h/32)*32;
inner = zeros(w1,h1);
for i=1:32:w1
    for j=1:32:h1
        a=i+31;
        b=j+31;
        F=fft2( I(i:a,j:b) );
        factor=abs(F).^f;
        block = abs(ifft2(F.*factor));
        larv=max(block(:));
        if larv==0
            56
        l   arv=1;
        end;
        block= block./larv;
        inner(i:a,j:b) = block;
    end;
end;
final=inner*255;
final=histeq(uint8(final));

error is shown:

Error: File: shottered.m Line: 1 Column: 8
Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error.

What is line 1 of shottered.m?

image is a built-in function and that may be the problem -- it's expecting input arguments for the image. Don't use image as your variable name. Call it inputImage or something.
