I downloaded your file matlab.mat , and using the MATLAB function image it created a lovely figure showing some torso cross-section, like from a CT scan.
What is the problem with the image? What exactly do you mean by "image equation"? What is the function f ? What are the variables x and y ? How should the image be different?
Do you wish to scale, resize or skew the image?

Do you possibly mean imresize()?
[rows, columns, numberOfColorChannels] = size(im);
% Get new x-width and y-height using formulas x/8 , y/12
% Remember, arrays are (rows, columns) = (y, x) NOT (x,y)!!!!!!!!!!
newRows = round(rows/12); % New y height
newColumns = round(columns / 8); % New x width
% Resize image
resizedImage = imresize(im, [newRows, newColumns]);

hamed, see my attached demo where I compute the first 4 image moments, mean, standard deviation, skewness, and kurtosis.
