MATLAB: Print column value for lowest element in each row of an 2D array

MATLABprint column index

I have a 2D array 20 X 10 double. Each row has a lowest figure. I am trying to obtain the column index of the minimum element in each row. I do not need the row index, just the column index. An elegant solution was provided ([~,idc] = min(A,[],2). It is able to be displayed. However, I am now having difficulty using fprintf to print the solution.Assistance appreciated

Why do you want to fprintf the result? Anyway, try:

fprintf('%d\n',idc);

MATLAB: Obtain column value for lowest element in each row of an 2D array

If you want to get the column indices, then this is the second output from min, when you work along the second dimension:

[vec,idc] = min(A,[],2)

For example:

>> A = randi(9,3,4)
A =
   3   9   6   3
   9   6   3   2
   6   3   6   7
>> [vec,idc] = min(A,[],2)
vec =
   3
   2
   3
idc =
   1
   4
   2

vec contains the minimum values for each row. idc contains the corresponding column indices.

The second output of min() gives you this:

[minx,idx] = min(A,[],1);
