Hi,
I am trying to get lowest postive number from array , and it's index,
I got the correct lowest postive number but due to introducing of greater than sign >, the indicies numbering changed, can anyone tell me how could I obtain lowest postive number with keeping and getting correct index...
I attach the code below... (Please remember it's a part from a code, and i need to get the values as written below)
clearvars;
clc;
S=[-6.3e7 -0.0001e7 inf;5.2545 -.2996e7 inf];
[m,idx]=min(S(S(:)>0)); % THE RESULT IS CORRECT BUT INDEX IS WRONG ... INDEX SHOULD BE 2
% I UNDERSTAND NOW THE INDEX IS CHANGED AS I INTRODUCED >0 BUT I WOULD LIKE TO GET THE INDEX FROM S(:) NORMAL

S=[-6.3e7 -0.0001e7 inf;5.2545 -.2996e7 inf]
m_idx = [min(S(S>0)), find(S==min(S(S>0)))]

S=[-6.3e7 -0.0001e7 inf;5.2545 -.2996e7 inf]
[m, idx] = myFun(S)
function [m, idx] = myFun(S)
m = min(S(S>0));
idx = find(S==min(S(S>0)));
end
