Benchmark Lab04: Multiplying Matrices, Graphing with Gnuplot

1. Save this starter program to your account.

2. Compile and run this starter program. The output should look something like this

3. To write your results to a text file:
   ./starter > timing.txt
   (this takes the screen output and writes it into the file timing.txt)

4. Plot your results with Gnuplot
   • Download this gnuplot command file
   • load gnuplot: "gnuplot"
   • Run the above file to graph your data: gnuplot> load "timing.gnuplot"
   • Rerun the program several times and replot the data each time. Different results?

5. Rewrite the starter program so that it multiplies two square matrices:
   C = A X B where A, B, and C are square matrices

6. Graph your results with Gnuplot
