hhead.mis the function for computing the tensor \head{H}.varian.mis the function for computing the random walk variances of linear system x = Hx+b.script.mis the script code for various experimental tasks described in the paper. Task 1: compute the success ratio. Task 2: compute the speed up ratio.
Please refer the the demo code blocks in script.m:
- compute success ratio for synthetic experiments.
- plot the success ratio for synthetic experiments.
- compute the speed-up ratio for synthetic experiments.
- compute the average speed-up ratio for the Harwell-Boeing sparse matrix collection.
