Description

This block is a single step discrete integrator. The output vector is the integral of the input vector computed with the first order forward Euler method define by the following formula: y(k) = h * u(k - 1) + y(k - 1), where h is the time step, y(k) the output vector and u(k - 1) the input vector at the previous sample instant.

Dialog Box

• Step : scalar. The integration time step.
• Initial state : a real vector. The initial value of output state.

• continuous-time state:no
• discrete-time state:yes
