Here is a part of code for fractal image compression and I am getting "Unrecognized function or variable 'create_transform'" error. How do I fix it?

Unrecognized function or variable 'create_transform'

Error in FIC_1 (line 101)

[temp_scale, temp_mse, temp_average] =

create_transform(original_input_image, row, column, range_size);

for row = 1:range_size:original_height
    for column = 1:range_size:original_width
         if fractal_mse(row, column) <= mse_tolerance && ...          
            fractal_mse(row,column+half_range_size) <= mse_tolerance && ...
            fractal_mse(row+half_range_size,column) <= mse_tolerance && ...
            fractal_mse(row+half_range_size,column+half_range_size) <= mse_tolerance
        
        % Transforms for row and column
        
        
        [temp_scale, temp_mse, temp_average] = ...
            create_transform(original_input_image, row, column, range_size);
        if temp_mse <= mse_tolerance
            
            fractal_scale(row, column) = temp_average;
            
            fractal_mse(row, column) = temp_average;
     
            fractal_average(row, column) = temp_average;
            
            fractal_size(row,column) = range_size;
            
            fractal_filled(row,column) = 1;
            
            fractal_filled(row,column+half_range_size) = 0;
            
            fractal_filled(row,column+half_range_size) = 0;
            
            fractal_filled(row+half_range_size,column)= 0;
            
            fractal_filled(row+half_range_size, column+half_range_size) = 0;
            
        end
         end
    end
end

Thanks for your response, I found it in a book, I made a seperate function in a seperate matlab file and then trying to call this function.

%% Create_Function
function finalanswer = create_transform(original_input_image, row, column, range_size)
end

Now I am getting this error.

Error using create_transform

Too many output arguments.

Error in FIC_1 (line 104)

create_transform(original_input_image, row, column,

range_size);

I will apreciate your help making this function.

Thanks, I fixed it.

%% Create_Function
function [temp_scale, temp_mse, temp_average] = create_transform(original_input_image, row, column, range_size)
temp_scale = 0;
temp_mse = 0;
temp_average = 0;
end
