Find column index of minimum value from 2D arrays

Question

Suppose I have a 2D array like this :

Array = [1 2 3; 5 1 6; 4 3 2]

I want to find the minimum value between each row, and save the column index of that result. I want my answer's like this :

ans = [1; 1; 2]

and the index :

column_index = [1; 2; 3]

Can somebody please help me? Thank you.

You are looking to find the minimum values along the second dimension. Use min -

[minval,column_index] = min(Array,[],2)
