Hi!
I need help with this code:
clc;clear;close all;a=input('Enter the real value of load impedance ZL, a=');b=input('Enter the Imagninary value of load impedance ZL, b=');ZL=a+1i*b;disp(['ZL=',num2str(ZL),'ohm']);a1=input('Enter the real value of characteristic Impedance Z0, a1=');b1=input('Enter the imaginary value of characteristic Impedance Z0, b1=');Z0=a1+1i*b1;disp(['Z0=',num2str(Z0),'ohm']);disp('Enter the R- To determine the Voltage reflection coefficient');disp('Enter the V- To determine the VSWR');disp('Enter the Z- to determine the impedance Zx from load');c=input('Enter your choice','s');switch c case 'R' rc=(ZL-Z0)/(ZL+Z0); x=real(rc); y=imag(rc); q=sqrt(x^2+y^2); VSWR=(1+q)/(1-q);disp(['The VSWR is',num2str(VSWR)]); case 'Z' zx=Z0*((ZL+1i*Z0*tan((2*pi)*0.35))/(Z0+1i*ZL*tan((2*pi)*0.35))); disp(['The Zx from load ZL is ',num2str(zx),'ohm']); otherwise error('invalid choice');end
I do not wish for the program to just end with an 'Invalid Choice' statement. I would like to program to loop back automatically prompting me to re-enter the parameters starting from Line 4. I am unsure on how to use syntaxes such as "if-else" or "for" or "while" to execute this. Please help!! Thank you 🙂
