Documentation of zoh vs linear interpolation

I am using Simulink and its associated viewer. I am viewing continuous time signals. I think I know what is going on, but is there any documentation about the zoh vs linear interpolation?

I am not sure I understand exactly what you are asking, as the description is a little vague. I have included documentation below for the Zero-Order-Hold block and the Interpolate block that includes an Interpolation mode parameter with a linear option:

I hope this helps.

From Workspace (and possibly other blocks) need to know what to output in-between the times specified with the data. The two main possibilities are to keep using the same signal until the new time (zero-order hold), or to interpolate the signal linearly between the old value and the new value (linear)
