Struct contents reference from a non-struct array object.

I am writting a code and in the last line of the code it shows the error "Struct contents reference from a non-struct array object.". Here is my code:

fic='cam2_person015.png';
img=imread(fic);
ti=size(img);
figure(1)
imshow(img);

normImage = mat2gray(img);
figure; imshow(normImage);

[x,y] = find(img);
lambda = 10.^(-9);
% lambda = eig(shadow);
meu = 10.^6;
H = heaviside(-y);
e = 1;
ee = e.^-((sqrt(x)/2.*sqrt(lambda))+(sqrt(y)/2.*sqrt(meu)));
anisotrophic_filter = img.*normImage.H.x.ee;

Kinldy check this. I shall be very thankful for the kind act of consideration.

[madhan ravi]

anisotrophic_filter = img.*normImage.*H.*x.*ee;
 %                                   ^--^--^-- missing

I am implementing the attached paper part 'C' --> "Extraction of RSD_HOG Feature".

kindly check the attachment and guide me.

Madhan Ravi while implementing this it gave the error:

Error using .*

Integers can only be combined with integers of the same class, or scalar doubles.

Error in RSD_HOG (line 21)

anisotrophic_filter = img.*normImage.*H.*x.*ee;

[KSSV]

Check the class of img....it could be integer.....convert it to double using double.

[Shah Bano]

Now it gives the error

Error using .*

Matrix dimensions must agree.

Error in RSD_HOG (line 22)

anisotrophic_filter = img.*normImage.*H.*x.*ee;

@Shah Bano: Then use the debugger to check the sizes of the array. We cannot guess this detail.

By the way, 10.^(-9) is an expensive power operation, while 1e-9 is a cheap constant. The runtime will not matter here, but it is a good programming practice.
