mean

Mean of array elements.

📝 Syntax

• R = mean(M)

• R = mean(M, d)

• R = mean(M, 'all')

• R = mean(M, d, t)

• R = mean(M, 'all', t)

• R = mean(M, d, t, f)

• R = mean(M, 'all', t, f)

📥 Input argument

• M - an array of double, single, integers, ...

• d - dimension to operate along: positive integer scalar.

• t - a string: 'default', 'double' or 'native'.

• f - a string: 'includenan' or 'omitnan'.

📤 Output argument

• R - Mean of array elements.

📄 Description

R = mean(M) returns the mean (average) of the array elements of M.

The arithmetic mean of a set of values $x_1, x_2, \ldots, x_n$

is defined as: $\bar{x} = \frac{1}{n} \sum_{i=1}^{n} x_i$

where $n$

is the number of elements.

💡 Example

M = uint8([10:30:70;20:30:80;30:30:90]);
R = mean(M, 'native')
