# The integration block in matlab

• MATLAB
I am new to matlab. There's a small thing that I am not aware of: why the integration block in simulink has the symbol as 1/s?

The Laplace transform of $$\int_0^t f(\tau) d\tau$$ is equal to $$\frac{1}{s} F(s)$$, where F(s) is the Laplace transform of f(t). Thus integration in the time domain is equal to multiplication by $$\frac{1}{s}$$ in the s-domain.
