I am having two matrices
A=[1.6512 1.6149 1.5829 1.5546 1.5298 1.1498 1.1334 1.1191 1.1066 1.0957 1.0862 1.0779 1.0707 1.0644 1.0589 1.0541 1.0499 1.0462 1.0430 1.0402 1.0377 1.0356 1.0337 1.0320 1.0305 1.0292 1.0198 1.0198 1.0198 1.0198 1.0198 1.0198 1.0198 1.0198 1.0198 1.0198 1.0198]
B=[ 2.7076 2.7629 2.7701 2.7939 2.7964 2.8101 2.8152 2.8153 2.8182 2.8183 2.8351 2.8389 2.8401 2.8483 2.8562 2.8581 2.8599 2.8638 2.8664 2.8691 2.8796 2.8817 2.8818 2.8841 2.8849 2.8849 5.2814 5.2834 5.2836 5.2875 5.2897 5.2946 5.3016 5.3102 5.3211 5.3254 5.3417 5.3484 5.3522]
Matrix A contains same value by reaching convergence after certain values.
I want to make matrix B to have the same value at the place where matrix A begins to have similar values .
Could anyone please help me on this

I want to have the B matrix in the following manner.
B=[2.7076 2.7629 2.7701 2.7939 2.7964 2.8101 2.8152 2.8153 2.8182 2.8183 2.8351 2.8389 2.8401 2.8483 2.8562 2.8581 2.8599 2.8638 2.8664 2.8691 2.8796 2.8817 2.8818 2.8841 2.8849 2.8849 5.2814 5.2814 5.2814 5.2814 5.2814 5.2814 5.2814 5.2814 5.2814 5.2814 5.2814 ]

ix = find(abs(diff(A)) < YourThreshold, 1, 'first') % maybe you want to add + 1
B(ix:end) = B(ix)

You should set/replace YourThreshold to/by some value ... I also suggest you read the getting started section of Matlab first :-)

Looks like it's the same as your previous question , why not use it then??
[~,~,c]=unique(A,'stable');
B = B(c)

Please don’t ask the same question multiple times ? Is it like a habit? It indeed is daunting. It’s clear that you’re doing project which is important, but at the same time you need to be patient. Your total number of questions account to 213, but considering the unique cases it would only count below 50.

From previous questions is has become abundantly clear that Jaah and their colleague Prahba have some difficulty using this website. I have suggested multiple times they should ask someone for help that can come to their physical location and that speaks their native language.
