在 MATLAB Online 中打开

function m=gaussian(med, var, n)
if ( mod(n, 2)==0 )
    n=n+1;
end;
med=double(med);
var=double(var);
med = min (max(-(n+1)/2, med),  (n+1)/2);
m=zeros(1,n);
k1=(1/(2*pi*var)^0.5);
k2=-0.5.*((med-(1:n)).^2)./var;
m(1,1:n)=k1.*exp(k2);
Output
 >> gaussian([101 2 ; 3 4], [4 301 ; 2 1], [2 2])
 error: gaussian: operator /: nonconformant arguments (op1 is 1x1, op2 is 2x2)
 error: called from
    gaussian at line 13 column 5
