MATLAB: How to sort new vector of the result of sum smallest probability

arraymatricesmatrixvector

I have matrix A with 10 probabilities. Then, I get the smallest probability index which is 9 and 10

A=[0.7188 0.0625 0.0625 0.0469 0.0313 0.0156 0.0156 0.0156 0.0156 0.0156]
index = find(ismember(A,min(A)));
B = index(end-1:end); % sucessfully run

After that I need to add the two smallest probabilities and named as C1 and delete the two smallest probability.

C1= A(9) + A(8); %C1= 0.0312

Then I need to sort the probability again in descending order.

A=[0.7188 0.0625 0.0625 0.0469 0.0313 C1 0.0156 0.0156 0.0156 ]

MATLAB: Could anyone help me how to select four maximum values of each row in a matrix size(10,8)

You can do it in multiple ways, let’s consider, the mat1 is matrix having size 10x8

sort_mat=sort(mat1);
result=sort_mat(7:end,:);

Another way as per @madhan ravi comment

sort_mat=sort(mat1,'descend');
result=sort_mat(1:4,:)

See example

>> mat1=rand(10,8)
mat1 =

Don't think of doing it see https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval use cell instead:

A= {0.7188 0.0625 0.0625 0.0469 0.0313 0.0156 0.0156 0.0156 0.0156 0.0156};
