min

Arguments

A

real vector or matrix.

A1,...,An

a set of real vectors or matrices, all of the same size or scalar.

Description

For A, a real vector or matrix, min(A) is the largest element A. [m,k]=min(A) gives in addition the index of the minimum. 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 minimum of the j th column of A (A(:,j)), k(j) gives the row indice which contain the minimum for column j. 'c' is used for the dual operation on the rows of A. 'm' is used for compatibility with Matlab.

m=min(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)= min( Aj(i)), j=1,...,n. [m,k]=min(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 minimum.

[m,k]=min(list(A1,...,An)) is an equivalent syntax of [m,k]=min(A1,A2,...,An)

Examples

[m,n]=min([1,3,1])
[m,n]=min([3,1,1],[1,3,1],[1,1,3])
[m,n]=min([3,-2,1],1)
[m,n]=min(list([3,1,1],[1,3,1],[1,1,3]))
[m,n]=min(list(1,3,1))
