app.Input_voltage_magnitude.Value= abs(Input_voltage);
That code assumes that app.Input_voltage_magnitude is a control of some kind, perhaps a text field
app.Input_Power.Value=app.Input_voltage_magnitude*I_input_magnitude*Power_factor1;
but you cannot multiply a control by anything.
This tells us that you are confused about whether it is a numeric value or a control.
