Hi everyone
I have a question regarding to the use of the minimum function (min()). Is there a such function that finds which element is smaller while comparing two elements from two different array (I know this can be done by using min() function), and then to find out which array is this minimum value is from.
For example, I have two arrays
a = [0 , 0 , 0 , 0.5 , 0.8 , 1];
b = [0 , 0 , 0.2 , 0.6 , 0.8 ,1.2];
Both array consisting 6 elements.
Then I used a for loop to find
for i = 1 : 1 : size(a,2)
minValue(1,i) = min(a,b);
end
Is there a way that I can find which array is the element of minValue() array is from?
For example, the third element of minValue() is taken from array 'b', is there a function to do that?
Thank you very much for your help
Tommy

The third element of b is not the minimum

[out,idxarr] = min([a;b]);
