The parameters for evaluation of the algorithm are CPU usage and throughput so how should I go about it
How to get the exact CPU usage in percentage to run a program in MATLAB?

I have implemented several cryptographic algorithms like DES and AES and would like to know the exact CPU usage and the throughput of the algorithm. How will I be able to calculate the throughput as well as the CPU usage of the algorithm.

It is quite tricky to model CPU usage on modern computer systems, and it is effectively impossible when you add the layer of MATLAB as we have little information about how exactly MATLAB does its computations.
The best you are going to be able to do is to measure actual CPU usage over a number of tests. See the timex contribution in the File Exchange.

With Process Explorer ( http://technet.microsoft.com/en-us/sysinternals) you can get way more information than you can probably digest. So much in fact that it will be hard to extract out just the MATLAB stuff. You'd be surprised at how many things are going on at one time in a computer - just run Process Explorer to see.

What is "the CPU usage" exactly? It can depend heavily on the CPU type, the number of unused cores, the number of other threads running in parallel and the cache sizes.
You can measure the runtime of a function by some TIC/TOCs, e.g. by FEX: timeit. The processor load can be determined by e.g. FEX: system-information-class-for-windows.
