maxi — maximum
[m [,k]]=maxi(A) [m [,k]]=maxi(A,'c') or [m [,k]]=maxi(A,'r') [m [,k]]=maxi(A1,A2,...,An) [m [,k]]=maxi(list(A1,A2,...,An))
| A | : real vector or matrix. |
| A1,...,An | : a set of real vectors or matrices, all of the same size or scalar. |
For A, a real vector or matrix, maxi(A) is the largest element A. [m,k]=maxi(A) gives in addition the index of the maximum. A second argument of type string 'r' or 'c' can be used : 'r' is used to get a row vector m such that m(j) contains the maximum of the j th column of A (A(:,j)), k(j) gives the row indice which contain the maximum for column j. 'c' is used for the dual operation on the rows of A.
m=maxi(A1,A2,...,An), where all the Aj are matrices of the same sizes,returns a vector or a matrix m of size size(m)=size(A1) such that m(i)= max( Aj(i)), j=1,...,n. [m,k]=maxi(A1,A2,...,An) gives in addition the vector or matrix k. for a fixed i, k(i) is the number of the first Aj(i) achieving the maximum.
[m,k]=maxi(list(A1,...,An)) is an equivalent syntax of [m,k]=maxi(A1,A2,...,An)
[m,n]=maxi([1,3,1]) [m,n]=maxi([3,1,1],[1,3,1],[1,1,3]) [m,n]=maxi([3,-2,1],1) [m,n]=maxi(list([3,1,1],[1,3,1],[1,1,3])) [m,n]=maxi(list(1,3,1))
