Putting array in function to graph

I am trying to graph this using the M array as input values

%For graph

x = 0 : 0.1 : 2;

y = 0.7*(x.^2)*(1+0.2*(x.^2))^-3.5

figure(1)

plot(x,y)

grid

This error is returned:

Error using ^ (line 51)

Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power

is a scalar. To perform elementwise matrix powers, use '.^'.

Error in aero (line 3)

y = 0.7*(x.^2)*(1+0.2*(x.^2))^-3.5

It was also not working trying to retrive N's values and not graphing. What am I doing wrong?

[KSSV]

x = 0 : 0.1 : 2;
y = 0.7*(x.^2).*(1+0.2*(x.^2)).^-3.5 ; 

y = 1×21
