How drow this founction in matlab in 3D plotting

[Dyuman Joshi]

Which function? Do you mean the expression of Complexity? There's only 1 independent variable i.e. "n". How would you plot a 3D graph from that?

If you want to plot the expression, you can do it like this -

fun = @(n) 6.^(n-1).*(n+4).*(n+6).^4;
fplot(fun)
