How to build K gaussian channel code in matlab ? i mean if $h_1,h_2,...,h_K$ are all gaussian channel,how do i write this code in just one or two line code?I know how to write the code if there is just one gaussian channel
But i think it is stupid to write as
then h=[h_1 h_2 h_3 ...h_k]
Does anyone know the better (smarter ) way to write this code?

There are many ways to do something like this. You can either fill your array by using cellfun, or a loop, or a direct calculation.
Your input to the randn function seems a bit strange, as you can't mix the scalar input type with the vector input type.
%assuming you meant randn([1 size(x)]) and h=[h_1;h_2;h_K]
h_k=@(k) sqrt(1/2)*(randn([1,size(x)])+1i*randn([1,size(x)]));%adapt to your needs
h=1:K;%reshape to whatever shape you need
