Change the "y=...." line to:
y=8*sinc(8*t)-4*sinc(2*t).*cos(6*pi*t);
Note the use of ".*" instead of "*" for the second multiplication. "*" is for
matrix multiplication while ".*" is used for element-by-element multiplication
of the two operands.
The print statement should just be "print("f:\yef.png")" to print the current
figure.
