Hi everyone, I want to reduce remove rows in matrix A, by referencing on the first number in each row to get B. In this case, if the first number is 1, remove the row
A = [1 1 1 0
0 1 1 1
0 1 1 0
1 0 1 0];
Results B =
B =[0 1 1 1
0 1 1 0];

index = 1;
% A(:,1) == index finds the rows with specific value (logical indexing)
B = A(A(:,1) == index,:)
