Hello all,
this should really be easy for you... I need AWK to print column maxima for each column of such input:
Input:
1 2 3 1
2 1 1 3
2 1 1 2
Output should be:
2 2 3 3
This does the sum, but i need max instead:
{ for(i=1; i<=NF; i++)
sum +=$i }
END {for(i=1; i in sum;... (3 Replies)

Basically I wrote code like this:
select * from `Test_DC_Trailer` HAVING max(DR_RefKey);
Where the DR_RefKey is a unique numeric field that is auto iterated (like a primary key)... (7 Replies)

DESCRIPTION
Each of these functions finds the maximum value of all elements in a matrix.
It uses the following equation:
max[0] = MAX{ x[i] i = 0, 1, ..., (m*n - 1) }
PARAMETERS
Each of the functions takes the following arguments:
max Pointer to the maximum value.
x Pointer to the first element of the source matrix.
m Number of rows in the source matrix.
n Number of columns in the source matrix.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
