You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: kernel_disperse.m
    path of file: ./repos/voltaML-fast-stable-diffusion/data/scalecrafter/disperse
    
    the code of the file until where you have to start completion: function R = kernel_disperse(smallSize, largeSize, inputSize, scale, eta, verbose)
    % Solve the convolution dispersion transform 
    % Params:

    
function R = kernel_disperse(smallSize, largeSize, inputSize, scale, eta, verbose)
    % Solve the convolution dispersion transform 
    % Params:
    %   smallSize: size of the input kernel     (i.e. 3)
    %   largeSize: size of the output kernel    (i.e. 5)
    %   inputSize: size of the input feature    (i.e. 7)
    %   scale: perception field enlarge scale   (i.e. 2)
    %   eta: the weight combining structue-level and pixel-level
    %   calibration                             (i.e. 0.05)
    %   verbose: whether to deliver a visualization
    % Outputs:
    %   R: dispersion linear transform
    if ~exist('verbose', 'var'), verbose = false; end
