% legend() function
x = 0:0.5:4*pi;
y = sin(x);
h = cos(x);
w = 1./(1+exp(-x));
% when i run program, it shows that Unrecognized function or variable 'g'.
% while there are g function on mathwork in Two-dimensional line plot module

In the following call of your code snippet,
you are trying to plot variable 'g' against variable 'x' among other, but you never define variable 'g'. You can see this by typing the following command which reveals all variables existing in your Base Workspace,
the output of which in your case is as follows,
Name Size Bytes Class Attributes
h 1x26 208 double
w 1x26 208 double
x 1x26 208 double
y 1x26 208 double
As you can see variable 'g' is nowhere to be seen.
I hope this helps.
