will hdl coder generate ram for 2 dimension array if isempty(my_ary)
my_ary = zeros (10,1000)
end
new_value = [1:10];
%later assigna a column in my_ary as follows
my_ary(:,2) = new_value;
Will hdlcoder generate 10 different RAM blocks

RAM mapping is an area optimization that maps storage and delay elements in your MATLAB® code to RAM. Without this optimization, storage and delay elements are mapped to registers. RAM mapping can therefore reduce the area of your design in the target hardware.
You can map the following MATLAB code elements to RAM:
