IC

Set the initial value of a signal.

Signals & Systems

Description

The IC block sets the initial condition of the signal connected to its output port.

For example, these blocks illustrate how the IC block initializes a signal labeled "test signal."


At t = 0, the signal value is 3. Afterwards, the signal value is 6.

The IC block is also useful in providing an initial guess for the algebraic state variables in the loop. For more information, see Chapter 10.

Data Type Support

A IC block accepts and outputs a signal of type double.
