Understanding initial behavior of Requirement Table

I am trying to understand the behavior of requirement table on initialization i.e. time = 0. The results are not what I am expecting, please provide some insight regarding this.
Issue: I have created a simple requirement table in which my output is difference of current Input value and previous input value(image1). Since I can not set initial value for my input, I decided to set initial value of my output(image2). But when I simulate the table, model does not reflect the set initial value and always shows output "0"(image3).
Expected Value: the initial value that I set should be the output at time = 0

In R2022a, the getPrevious function is undefined at t = 0 so you will need to an alternative, such as isStartup, to handle that condition.
In R2023b, initial conditions are now supported and can be specified for u in the Property Inspector. See latest behavior here:
Hope this helps,
Josh
