Math Forum / Math Software / MATLAB / July 2008finding position in an array??
Hi please can anyone help me with this issue I have array like c c=[1 2 5 1 9 6 0 4] by using max (max(c)) function we can find the largest number in this array (9), but how to find its position, which must be c(1,5)?? thank you Okay, well I suppose a fairly intuitive way of doing it would be to find the max first. MAX = max(c) Then you want to find where this max occurs within c. You can do this using the "find" command. Check the help section of matlab for more details. LOCATION = find(c == MAX) will return a single number indicating how far into the matrix the max occurs. In this case, LOCATION would be 5 (the fifth element of c). But find can all return more than 1 value. [ROW,COL] = find(c == MAX) COL will be what column the max occurs in and ROW will be what row it occurs in. So here ROW= 1 and COL= 5. Thank you for your replay But is it the same if I want to search a certin row in an array?? Must it be like this MAX=max(c(i,:)) and what to put instead of the --- bellow find(--- == MAX) > Thank you for your replay > [quoted text clipped - 7 lines] > > find(--- == MAX) Read the help for max, and pay attention to the 3rd possible input and the 2nd output.
