Syntax

[L]=isapprox(A,B,tolLevel);

Description

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;

Examples

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
