max
Maximum elements of an array
Syntax
Description
returns the maximum elements of an array.M
= max(A
)
If
A
is a vector, thenmax(A)
returns the maximum ofA
.If
A
is a matrix, thenmax(A)
is a row vector containing the maximum value of each column ofA
.If
A
is a multidimensional array, thenmax(A)
operates along the first dimension ofA
whose size does not equal1
, treating the elements as vectors. The size of this dimension becomes1
while the sizes of all other dimensions remain the same. IfA
is an empty array whose first dimension has zero length, thenmax(A)
returns an empty array with the same size asA
.
___ = max(___,'ComparisonMethod',
optionally specifies how to compare elements for any of the previous syntaxes.
For example, for a vector method
)A = [-1 2 -9]
, the syntax
max(A,[],'ComparisonMethod','abs')
compares the elements
of A
according to their absolute values and returns
-9
