Function to output multiple figures

I am trying to write a function that could output multiple figures

function [fig1,fig2] = FunctionName(Input1,Input2,Input3)

   ...
   fig1=surf(...)
   fig2=surf(...)
end

But the returned value of fig1 and fig2 do not seem to be a graph. Did I do anything wrong?

Solution:

function [fig1,fig2] = multiplot()

fig1 = figure();
surf(rand(15));
fig2 = figure();
surf(magic(15));

end

Explanation: second call to surf overwrote the data in the figure created by the first call to surf.
