    i need help, i asked to do simulation of half wave uncontrolled rectifier with R-L load with matlab for R=100 ohm and L=10 mH , i built the schematic and run but output is different about we study.
    here the file i created with matlab 2013

    A) None of your work is labeled.
    Three plots in RL_out don't tell me jack.

    B) What frequency are you using?
    I did a sim using MultiSim and at 60 Hz there is not much to see. Then I tried 200 Hz and I saw VL like they show it in your book illustration VL=VO-VR.

    Vout is red. Vresistor is green. Vinductor=Vout-Vresistor=975.4-678.1= about 300 mV.

    i am sorry the source is ac its value 220 RMS and frequency is 50 Hz
    the first graph is V out
    the second is I
    the third is diode voltage and current
