Is there any function/command to replace unit delay function block in matlab?

I am currently, trying to run simulink models by writing a program in MATLAB. The issue is that the outputs of one of the model acts as an input of a previous model and hence requires use of delay input. Instead of creating that block in the model, I want to run everything through a program.Please check the attached image

In the image, I am currently using delay input block to achieve the desired functioning. Is there a way of removing it and specifying delay input via MATLAB command/function?
