MATLAB: I want to find in which row the minimum element is

minimum in vectorrow

I have a vector and i wand to find in which row i have the lowest number

Best Answer

Use the min function with two outputs:

[Vmin,Idxmin] = max(V);

If ‘V’ is your column vector, ‘Vmin’ will be the minimum value, and ‘Idxmin’ will be the index of the first occurrence of the minimum. If you have more than one value of the minimum, use the find function:

Idxmin = find(V == min(V));

It will return the indexes (row numbers) of all values of the minimum.

It's because in your second calling of the function

[maxV, minV] = myFunction(volume, bins)

you are setting the first output of your function ('distrib' in your function definition) to the variable 'maxV' and the second output ('maxV' in your function definition) to the variable 'minV'. You can call the first output variable whatever you want when you call the function, and it will take the value of the variable that is called 'distrib' in the function.

To illustrate, try this, for example:

volume = rand(3,3,3,3); bins = 5;
[distrib, maxV, minV] = myFunction(volume, bins);
[maxV, minV] = myFunction(volume, bins);  
isequal(distrib, maxV)  %this should be true.

Remember that the variable names when you call the function and the variable names inside the function are, in general, completely separate. If you just want to output the 'maxV' and 'minV' variables (the second and third outputs of your function), call it as such:

[~, maxV, minV] = myFunction(volume, bins);

The tilde (~) tells Matlab to skip that output variable.
