hpf filter

I wish to implement a discrete High-Pass-Filter (HPF) in Matlab/Simulink. I found a discrete Low-Pass-Filter (LPF) in one of the Simulink examples as follows:



Numerator: [1-exp(-2*pi*fc*Tsc)]z
Denominator: z-exp(-2*pi*fc*Tsc)

fc: cut-off frequency
Tsc: sampling period

Could someone pls shed some light how to implement a discrete HPF?

Thanks.
