In the IB callback function:

voltage = double(get(handles.edtVoltage, 'String'));
length = double(get(handles.edtLength, 'String'));
loadw = double(get(handles.edtLoad, 'String'));
IB = whatever equation you use...
% Put into edit field
str = num2str(IB);
set(handles.edtIB, 'String', str);

Change the names to whatever "tag" property you gave to the edit field controls.
