MATLAB: How to find max of a column and run it in a loop

helpMATLABmatrixmatrix array

device=[1 2 3 4 5 6 7 8 9 10]

block=[1 10;2 11;3 7;4 13;5 14]

new=block(block(:,1) == max(block(:,1)),:)

how to run this max value finding in a loop and display with adding elemnt from device array? like after first find output will be 1 5 14 and last output will be 5 3 7.

Why use find() when min() and max() are more directly suited for finding the min and max values and indexes:

A=[1,2,3,4,5;,6,7,8,9,10;11,12,13,14,15;16,17,18,19,20;21,22,23,24,25]
[firstRowMaxValue, firstRowMaxIndex] = max(A(1, :))
[firstRowMinValue, firstRowMinIndex] = min(A(1, :))
[lastColMaxValue, lastColMaxIndex] = max(A(:, end))
[lastColMinValue, lastColMinIndex] = min(A(:, end))
