Bench mark script with Simulink, xlsread and xlswrite

This bench mark problem was developed to compare the performance of various matlab release versions

The Bench_Sim.m scripts create a new model with 100 From Workspace, Gain and To workspace blocks. A standard set of inputs is read from the BenchTestInput.xls and these inputs are pumped into the Simulink model. The outputs obtained from the Simulation is accumulated and written into an xls file using xlswrite. This exercise is performed several times to average out the results. (Hardcoded to 10 in the script- jj=1:10).
This exercise is done to emulate batch processing a typical VnV activity. The Test Case inputs are written in Excel. A Simulink model is executed and the outputs are written back to the excel file.
The script gives out the execution time for the entire exercise. This timing is used to compare the performance of different Matlab/Simulink Versions.

Comparison of 2 different Matlab Versions are as shown below:
MATLAB Version: 8.1.0.604 (R2013a)[64 bit version]
Elapsed time is 56.774682 seconds.
MATLAB Version 7.7.0.471 (R2008b)[32 bit version]
Elapsed time is 34.360705 seconds.

Both evaluations were done on the same PC with the configuration as shown:
