build the following periodic source in Simulink

Anyone could suggest how to build the following periodic source in Simulink? The left part is sine wave

The period is 0.8 seconds. From 0 to 0.3 sec, it is a half sine function (positive half, period 0.6 sec) with amplitude 100; from 0.3 to 0.8, equal to 0

thanks:)

Define the time and data vectors in the MATLAB Workspace such as

>> t = linspace(0,0.8,100)';
>> u = 100*sin(pi/0.3*t);
>> u(t>=0.3) = 0;

then in Simulink use the Repeating Sequence source block with time vector set to be variable t and data vector set to be variable u.
