[Max,index]=max(array,[ ],2)..... Iam using this syntax to find the maximum value of every column but in case of two equal maximum values it returns the first one... how can I solve this?! Thanks

if A is a matrix, then max(A,[ ],2) is a column vector containing the maximum value of each row . What is this '2' for ? can anybody explain please. Thanks.

As clearly stated in the documentation for max, that "2" indicates the matrix dimension along which to take the maximum.

This code will return the row and column indices where the entry is equal to the column's maximum.
[rowIdx,colIdx] = find(A==max(A))
