TomSym has the ability to analyze p-code for possible performance improvements and validation.

The following example illustrates how TomSym can be used:

1. Create a file called pcodetest.m with the following text:

function y = pcodetest(a,b)

y = sin(a)+b.^2-30;

2. Call "pcode pcodetest" to generate a pcoded file and delete the original m-file.

3. Execute the following in Matlab:

>> toms 3x1 a b

>> pcodetest(a,b)

ans = tomSym(3x1):


4. The function has now been analyzed and the constant separated.

5. Create a new m-file with the code from TomSym.
