MATLAB: Finding minimum value of array with certain property

arrayMATLAB

Hello,

I have an array that I am using as the y values for a plot of mine. I want to identify the index where the y value first passes a certain value and the y value where it drops below a certain value. Is there a simple way I can do this? Essentially, I want to find the lowest index with a certain value and the index above which a certain value is never again reached.

You can use the find command.

idx= [diff(A(:,3)')==0 0];
ii2=find(idx==0);
ii1=[1 ii2(1:end-1)+1];
B=zeros(numel(ii1),size(A,2));
C=zeros(numel(ii1),2);
for k=1:numel(ii1)
  jj=ii1(k):ii2(k);
  [minv,jdx]=min(A(jj,1));
  B(k,:)=A(jj(jdx),:);
  C(k,:)=[mean(A(jj,1)) A(jj(1),3)];
end
B,C
