First I am not sure if HDL coder can generate VHDL and Verilog code. But I may point out that you can use dct instead of dct2 to ensure MATLAB coder works.

This is because dct2 is not supported by MATLAB Coder (see full supported function list here ).

But however dct is supported, conditionally. Therefore, in some cases you can separate dct2() as dct(dct().').' to compute dct2. For example a validation code looks like

N = 10;
x = rand(N,N);
max(max(abs((dct2(x) - dct(dct(x).').'))))

from which we get

ans = 
      0

So, you can first use two dcts to compute dct2 instead, and then generate your code using MATLAB coder.

In R2011b, the name of the HDL code generator was Simulink HDL Coder. It allows you to generate VHDL or Verilog code from Simulink designs. You can generate HDL from MATLAB in this release by placing the MATLAB code in a MATLAB Function block in a Simulink block diagram. The ability to generate HDL directly from MATLAB code was added in R2012a, at which point the product was renamed to HDL Coder.
