n = nume1(y); on the Matlab OnRamp dosen't work ?

Task 1 ✔ fs=10

fs = 10

   Task 2 ✔
t=[0:1/fs:20];
   Task 3 ✔
y = sin(1.8*2*pi*t)+sin(2.1*2*pi*t)

   Task 4 ✔
plot(t,y,'r-')
   Task 5 ✘

   Task 5 ✔
yfft = fft(y)

   Task 6 ✘
n = nume1(y)
Undefined function 'nume1' for input arguments of type 'double'.

n = nume1(y); Undefined function 'nume1' for input arguments of type 'double'. Task 6 ✘ n = size(y) n = 1 201 Task 6 ✘ N = nume1(y); Undefined function 'nume1' for input arguments of type 'double'.
