Just call this code to get minVelocity whenever you need it
minVelocity = str2double(handles.minVelocity.String);
The function will have to have access to the handles structure, which all GUI component callbacks will have.
See the FAQ for more options.

Replace this
% --- Executes on button press in execute_button.
function execute_button_Callback(hObject, eventdata, handles)
minVelocity = str2double(get(handles.minVelocity_text, 'string'));
% Store the data in the "UserData" property of the GUI Figure
% This assumes that the hObject is a child of the GUI figure
data.minVelocity = minVelocity;
hObject.Parent.UserData = data;
disp(minVelocity)
Analysis_Main
with this
% --- Executes on button press in execute_button.
function execute_button_Callback(hObject, eventdata, handles)
minVelocity = str2double(get(handles.minVelocity_text, 'string'));
% Store the data in the "UserData" property of the GUI Figure
% This assumes that the hObject is a child of the GUI figure
data.minVelocity = minVelocity;
hObject.Parent.UserData = data;
disp(minVelocity)
handles = Analysis_Main(handles);
