MATLAB: Could anyone help me to solve the issue

Question

A=[2.1     2.2     2.3     2.4     2.5     2.6]
B=[0.49     0.48     0.47     0.47     0.47     0.47]

I want to have the desired result

A=[2.1     2.2     2.3     2.3     2.3     2.3]

As B has the same values starting from third place, A needs to have the value 2.3 at the same third place and it should be continued until the end.

Answer 1

[~,~,c] = unique(B,'stable');
A = A(c)
