Passing piecewise-constant vector to Simulink

Hi,

I am trying to pass a piecewise-constant vector to my Simulink model but I do not know how to generate and use it in Simulink. To be more clear, I want to pass a vector like in the figure below containing the time steps and the values of "u" in each time step. I would really appreaciate it if someone could help me.

There are many ways. The easiest is to define time t=[t1, t2,...t5] and a=[a1,a2,...a5] in workspace and then use the "From Workspace" block, specify data as [t;a].' and do not intoperlate data.
