I have a 2D array 20 X 10 double. Each row has a lowest figure. I am trying to obtain the column value of the minimum element in each row. I do not need the row value, just the column value. I have searched an been able to find the minimum value but the forums do not show a way of obtaining individual row or column figures for a set value. Assistance appreciated

"Is there any way of using this solution with fprintf?"
fprintf('%d,',idc)
If you want some other formatting then following the guidelines in the fprintf help.

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.
