Matlab Question - please show code. Thank you

Complete the resistors function to compute the combined resistance of four resistors in parallel. he combined resistance R of four resistors R1... Rs in parallel is given by R-1 R R4 Input variables: r1, r2, r3, r4-scalar values containing the resistance of each component in the parallel circuit Output variables: R - a scalar containing the combined resistance. Function Template function R- resistors(rl, r2, r3, r4) %Calculate R here end Test Example Once you have finished writing the function in MATLAB, you should save it and then test it, by entering one of the commands below (depending on the number of resistors you had in your question), into the MATLAB Command Window at the Matlab prompt (>>) if you had 3 resistors in your question: entering resistors (100,200,300) should return 54.5455 if you had 4 resistors in your question: entering resistors (100,200,300,400) should return 48.0000; if you had 5 resistors in your question: entering resistors (100,200,300,400,500) should return 43.7956; if you had 6 resistors in your question: entering resistors(100, 200,300,400,500,600) should return 40.8163; f you had 7 resistors in your question: entering resistors ( 1 ee, 2, , 400, 500, 600, 780) should return 38 .5575
