F-test using vartest2 is giving a NaN

Here's that section of the code

h0 = 0.86192;

h1_m = 1/4;
h1_e = 1/3;

H_F_m = vartest2(h0,h1_m);
H_F_e = vartest2(h0,h1_e);

When displaying both H_F_m and H_F_e I get a NaN.

You are getting NaN value because your data size is just one element.To get more details regarding How MATLAB calculates Two sample F-Test , refer the link below :
