MATLAB: Matlab can’t recognize the 0.06 in array 0.01:0.01:0.1

bugfloating pointnot a bug

Hi,

I executed below cods (attached photo) in Matlab 2018 and the answer is wrong . I was using methode ismember for two sample but the answer for 0.08 is true and the answer for 0.06 is false.

I would like to know , how can I fix this problem.

codes:

————————————————————————-

A = 0.01:0.01:0.1;

disp(A);

B= 0.06 ;

C= ismember(B,A);

disp("0.06 is " +C)

D= 0.08;

E = ismember(D,A);

disp("0.08 is " +E)

————————————————————————–

Thanks

Ali

Use ismembertol()

MATLAB: Get in Order respond when using “eig” command

To sort the eigenvalues to be increasing in magnitude, use the following:

[U, d] = eig(k, m, 'vector');
[d, ind] = sort(d);
U = U(:, ind);

The eig function doesn't sort the eigenvalues it returns, for two reasons:

1) This is not needed for many applications, and would slow down the computation time for these cases. 2) For non-symmetric eigenvalue problems, the eigenvalues are complex, and none of the sorting methods for complex values are very satisfactory.

For symmetric problems (for the generalized case, this means both matrices are symmetric, and the second matrix is also positive definite), the eigenvalues are typically returned in ascending order by eig, but this is not a guarantee.

MATLAB: Is 0<0.01

0 < 0.01 in MATLAB, as expected. 0 > 0.01 would be unexpected.

Also, re-check whether your c1 or your eps become vectors. The behavior of if and while when testing a non-scalar is well-defined but often a surprise.
