i want to create a function that contains table and produces an output

i want to create a function that contains table and produces an output after comparing the variable name with the value present in the table

example

function name is compare

compare(a)

it produces 23

as it will be defined in function that

a=23

b=24 and so on

Does it need to be a function ? Does it really need to contain a table ?

Assuming that the "name" is a string (if it isn't then you can use inputname ), then there are several ways you could achieve this:

• given then names in your example 'a' and 'b', this will work for individual characters from 'a' to 'z':

name_string - 'a' + 23

this can easily be defined as a function:

>>fun = @(s) s-'a'+23;
>>fun('b')
ans = 24

• for more complicated name strings you could use a struct to achieve this functionality:

>>A = struct('aa',23,'bb',24);
>>A.('bb')
ans = 24
