max

---

Maximum elements of an array.

---

Syntax

---

M = max(A)

[M, I] = max(A)

M = max(A, [], dim)

[M, I] = max(A, [], dim)

M = max(A, [], dim, 'omitnan')

[M, I] = max(A, [], dim, 'includenan')

[M, I] = max(A, [], 'all')

[M, I] = max(A, [], 'all', 'omitnan')

[M, I] = max(A, [], 'all', 'includenan')

C = max(A, B)

C = max(A, B, 'omitnan')

C = max(A, B, 'includenan')

Input argument

---

A

a variable

dim

a positive integer scalar (Dimension to operate along)

'omitnan'

ignore all NaN values. default behaviour. max will return the first element, if all elements are NaN.

'includenan'

include the NaN values.

'all'

it finds the maximum over all elements.

Output argument

---

M

Maximum values of A.

I

Index to maximum values of A.

C

Maximum elements from A or B.

Description

---

max find maximum values in an array.

If A is a matrix then M = max(A) is a row vector containing the maximum value of each column.

If A is a vector then M = max(A) will return the maximum of A.

If A If A is complex number then M = max(A) will return founded complex number with the largest magnitude.

Example

---

A = [1 2 3; 4 5 6];
M = max(A)
M = max(A, [], 'all')
