I want plot the function A versus x, can't write the program for the following algorithm.
A= K for x <= 0; K is a constant
A= K/2 (1+cos x) for 0<x<50;
A= 0 for x >= 50
i have used the if elseif else end statement, but not not succeed.

K = 1;
x = linspace(-100,100);
A = K/2*(1 + cos(x));
A(x<=0) = 1;
A(x>=50) = 0;
plot(x,A)
