[Walter Roberson]

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.
