Copy the contents of file MMult0.c into a file named MMult1.c and change the contents:

|| from || to || ||<^> -Include(HowToOptimizeGemm/Details/MMult0)- ||<^> -Include(HowToOptimizeGemm/Details/MMult1)- ||

Change the first lines in the makefile to

NEW  := MMult1

• make run

octave:3> PlotAll        % this will create the plot
