Question

How to add the algorithm that finds the "convergence rate" of algorithms in MATLAB?

Answer 1

`Hey,

Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

There is no such clear cut formula to it. But, we can calculate the time taken by both algorithm and find the ratio to calculate the rate.

So, for example

clc%clears screen
clear all%clears history
close all%closes all files
format long
n=1000;
A=rand(n);
b=rand(n,1);
tic;
x=A\b;
t1=toc;
n=2000;
A=rand(n);
b=rand(n,1);
tic;
x=A\b;
t2=toc;
disp('Approx rate is');
t2/t1

Kindly revert for any queries

Thanks.
