MATLAB: How we can give Delay in a clock

delay in a clockPhased Array System Toolboxsimulink

Hi. I am using "Delayseq" function in MATLAB function block using simulink. But it doesn't provide delay in a clock. I cannot use ideal fixed unit delay block because, I need variable delay and later I have to adjust that delay. therefore, I am using this customized function. but it's not giving delay in a clock.
shifted_signal = delayseq(u,0.004,250);
here, I am giving delay 4ms and sampling frequency is 250. I set 250 because in clock generation block I set sampling time =4ms.
I attached the snaps please have a look and help in this regard. I really need help for this work. if anyone help it would be appreciated. Thanks

delayseq works on a vector, e,g.,
>> delayseq([1;0;1;0;1;0;1;0;1;0],0.004,250)
>> ans =

while if I under your model correctly, the pulse samples are generated one at a time, that's why the function is not providing the correct answer. You can consider adding a buffer in between to convert the signal to vector, but then you need to live with the fact that there is a latency due to the buffering at the output.
