Hi everyone. I have a problem with my code. I can’t write the normal distribution code, and after that plot that in 3D. I want you to continue line 21. Thanks.

clc
clear all
heightm = 175+7*randn(1,100);
heightm =sort (heightm);
weightm = 80+5*randn(1,100);
weightm =sort (weightm);
%TWO classes
heightw = 160+6*randn(1,150);
heightw =sort (heightw);
weightw = 60+4*randn(1,150);
heightw =sort (heightw);
%feature vector 2*1
feature_vectorm = [heightm;weightm ];
feature_vectorw = [heightw;weightw ];
% mij (mean vector)
m2m= mean(feature_vectorm');
m2w= mean(feature_vectorw');
