please help !! how can I covert this code to HDL with matlab

I = imread('cameraman.tif');
 I = im2double(I);
T = dctmtx(8); % dct matrix
%Performing DCT on blocks of 8 by 8
dct = @(block_struct) T * block_struct.data * T';
B = blockproc(I,[8 8],dct);
B = ceil(B); 
% A Standard Quantization Matrix
q_mtx =     [16 11 10 16 24 40 51 61; 
            12 12 14 19 26 58 60 55;
            14 13 16 24 40 57 69 56; 
            14 17 22 29 51 87 80 62;
            18 22 37 56 68 109 103 77;
            24 35 55 64 81 104 113 92;
            49 64 78 87 103 121 120 101;
            72 92 95 98 112 100 103 99];
   %PErforming Quantization by Dividing with q_mtx on blocks of 8 by 8
   c = @(block_struct) (block_struct.data) ./ q_mtx;        
   B2 = blockproc(B,[8 8],c);
  %    B2 = ceil(B2)
%Performing Inverse Quantization By Multiplying with q_mtx on Blocks of 8
%by 8
B3 = blockproc(B2,[8 8],@(block_struct) q_mtx .* block_struct.data);
%Performing Inverse DCT on Blocks of 8 by 8
invdct = @(block_struct) T' * block_struct.data * T;
% B3 = ceil(B3);
I2 = blockproc(B3,[8 8],invdct);
imshow(I), figure, imshow(I2)
