Undefined function or variable

Where am I going wrong with this function?

function Analysis(src,evnt)

f = figure('Visible','off','Position',[500 500 500 500]);

uicontrol('Style','pushbutton','String','Button','Position',[10,230,450,50],'Callback',{@Evaluate},'BackgroundColor','green');
axes('Units','pixels','position',[50 50 550 550]);

% Assign the GUI a name to appear in the window title.
set(f,'Name','Projectile Motion');
% Move the GUI to the center of the screen.
movegui(f,'center');
% Make the GUI visible.
set(f,'Visible','on');

function Evaluate(hObject, eventdata, handles)

Error code: ??? Undefined function or variable 'Analysis'.

What's the file saved as?

It should be saved as Analysis.m and should be on the MATLAB path or in the current directory.
