mean

Arithmetic mean.

Syntax

M = mean(A)
M = mean(A, dim)
M = mean(A, flag)

Description

Returns the arithmetic mean of A. With no second argument, averages along the first non-singleton dimension. With a numeric dim, averages along that dimension. The optional flag ('omitnan' / 'includenan') controls NaN handling — default is to skip NaN values.

Examples

mean([1 2 3 4 5])        % 3
mean([1 2; 3 4])         % [2 3]   column means
mean([1 2; 3 4], 2)      % [1.5; 3.5]   row means
