Thread Subject: Find all the minimum

Hey guys I need your help on this, I need to find all the positions where a minimum value occur. Lets say,

A = [120;113;116;196;113];

When you try to find the minimum,

MinValue = min(A);

you get a result as,

MinValue = 113

Now I want to be able to get the 113 value plus know that it occurs at A(1,2) and at A(1,5). How can I do this??

Thank you so much for your help and I hope I made myself clear!

Diego

Nevermind guys I found the solution to my question.

Just did,

Idxs = find(A==MinValue);

Thanks anyways!

The easy way is
[x,k]=min(A)

x is the minimum value
k is the index
See help min

Yes, see help min, which would show you that min() with two return arguments
only returns the index of the -first- minimum found (with respect to the
appropriate dimension.)

hey Aasim thanks for your suggestion but that does not work as it will only give you the first value, so 113. However what I wanted was to get where that value was if it was at more than one place so in this case I wanted to know that it was at 2 and 5 and the code I gave does that.

Thanks

Hi
In that case you can use my programs maxima and minima. you can download them from matlab file exchange
good luck
