How can I plot Bit Error Rate for ASK Modulation?

I don't understand how to plot Bit Error Rate for ASK Modulation in Matlab. Could you help me please?

Ny - you may want to check out Nikesh Bajaj's submission Digital Modulation ASK, PSK, FSK on the File Exchange. It looks to include a BER vs SNR rate which may give you an idea how to plot the bit error rate.
