Explanation / Answer

function R=decoderesistor()
%% Provide the three appropriate input the function
% here the fourth band is ignored.
ip1=input('Enter the first colour code letter ','s');

ip2=input('Enter the first colour code letter ','s');

ip3=input('Enter the first colour code letter ','s');
