MATLAB: How to convert file.m into block in Simulink

MATLABsimulink

hi,
I wrote a function that produce 40 binary bits vector according to another 20 bits vector. In Matlab it works ok.
I want to convert it into a blockqmodel in Simulink.
Anybody knows how to do it ?
for example:
function gate_h = gate_array(I_H, indx_h)  
no_cells = 20;    
if(I_H > 0) 
  TMP_reg = [zeros(1, no_cells-indx_h), ones(1, indx_h)]; 
else 
  TMP_reg = [ones(1, indx_h), zeros(1, no_cells-indx_h)];
end  
bitpatterns = {[0 1], [1 0]};
gate_h = cell2mat(bitpatterns(TMP_reg + 1));
Thanks, Henry

Try using the following as a MATLAB Function block
function gate_h = gate_array(I_H, indx_h)
no_cells = 20;
gate_h = zeros(1, no_cells * 2);
gate_h(1:2:indx_h*2) = 1;
gate_h(indx_h*2+1:2:no_cells*2-1) = 1;
if I_H > 0
  gate_h = 1 - gate_h;
end
