How to make sound analysis in Matlab?

I want to make a calculator using matlab.First I saving a lot of number as sound after then I take a sound and I find corresponding sound.Please help me on this.

Do you mean "take a sound and find the corresponding number" ? That is, recognizing the sound?

I do not understand how "calculator" is part of this?

Maybe it's like voice recognition where he has recordings of someone saying "one", "two" etc. and he needs to read in the recording and figure out what number was said???? Or maybe he wants to build a calculator and play different sounds depending on what number button was pushed (less likely possibility I think).

yes first you think , I say two number and then I am asking what action do you want to do . take it all for to send c# from matlab .After I calculate them at c# and use sound for explain this result. I hope to be understanding.

I didn't quite grasp it - perhaps if you got a better English speaker to proofread it. It sounds like you are going to say the number "two" into a microphone and want MATLAB (or some program) to digitize that, and then your MATLAB program will look at the digitized sound signal and determine that the sound wave corresponds to the number 2.

But then I don't know what you want to do with C#. Is that "C sharp" - the programming language from Microsoft: http://en.wikipedia.org/wiki/C_Sharp_%28programming_language%29? Or when you say " use sound for explain this result" do you want to play some "perfect reference" or template recording of the 2?

c# is difficult to call from MATLAB, apparently.
