data.a='u';
data.b='w'
x=input('input','s');
s=data.(x)

wow.. it works fine..thanks Abdel..

[Sivakumaran Chandrasekaran]

your answer suits the best for a single letter. now my input is siva. my answer should be tfjs. how to get it. next doubt is.. i can give any input of my own choice. it can be of any length of characters. to be in short, it should be as like encryption.

[Azzi Abdelmalek]

There is no difference

data.tfjs='siva';
x=input('input','s');
s=data.(x)

[Sivakumaran Chandrasekaran]

you fixed the word siva. i am not supposed to fix it... user may give any input

[Azzi Abdelmalek]

What do you mean? you said siva corresponds to tfjs. You have then to put it in your code or no? Or explain

[Azzi Abdelmalek]

Maybe you want this

data.a='u';
data.b='w'
x=input('input','s');
n=numel(x);
for k=1:n
 s(k)=data.(x(k))
end

It works well for a single word... how about for a sentence

You can create a lookup table:

pool = repmat(char(0), 1, 255);
pool('a') = 'u';
pool('b') = 'w';
...
% Or together:
pool('ab') = 'uw';  % A strange indexing, but it works

And then:

c = 'a';
pool(c)
