if i had four values. For example,
a=100
b=-100
c=30
d=100
and i wanted the variable ‘e’ to equal the value which has been repeated (100). how would a write a function that inspects the values of a,b,c and d, determines which two are the same and equates that to the output as e. (so in the exanple. answer is e=100)

You can use the function any to find out if any of the variables is equal to any other variable.
any(a==[b c d])
will gave a logical 1 if 'a' is matching with any of the other variables.
You can see how to write a function here.
