Below is a demonstration of the features of the isapprox function
clear; close all; clc;
This function returns if A is approximately equal to B (to within tolLevel) in the form of the logical L. In other words the function simply evaluates: L=abs(A-B)<tolLevel;
tolLevel=1e-4; % The tolerance level to use A = - pi; %Example number B = A + tolLevel/100; % Small difference C = A + tolLevel*100; % Big difference D = A + tolLevel; % Difference equal to the tolerance level
Using isapprox here should return a true since the difference is smaller than the tolerance.
L1 = isapprox(A,B,tolLevel)
L1 = logical 1
Using isapprox here should return a false since the difference is larger than the tolerance.
L2 = isapprox(A,C,tolLevel)
L2 = logical 0
Using isapprox here should return a false since the difference is equal not smaller than the tolerance.
L3 = isapprox(A,D,tolLevel)
L3 = logical 0
