length - Length of vector

Syntax

n = length(X)

Description

The statement length(X) is equivalent to max(size(X)) for nonempty arrays and 0 for empty arrays.

n = length(X) returns the size of the longest dimension of X. If X is a vector, this is the same as its length.

Examples

x = ones(1,8);
n = length(x)

n =
     8
x = rand(2,10,3);
n = length(x)

n =
    10
