The identifiers shot (all lower-case) and Shot (first letter capitalized) are two different things in MATLAB. Did you mean to index into Shot instead of shot?

The end operator must be used within an array index expression.
Error in test2 (line 5)
BER(i)=ber(end,1);
This is the code.
gama_dB=0:0.5:10;
for i=1:length(gama_dB)
g_dB=gama_dB(i);
sim('Bpsk2')
BER(i)=ber(end,1);
end
Why is this error coming here? plese help.

Nothing in your code defines a variable named ber. Do you have a function named ber accessible to MATLAB? If so that last command inside the for statement tries to call that function with end and 1 as the two inputs. But MATLAB doesn't know how to interpret end in that context and so throws an error.
