`strlength`

Number of characters in each string.

Category: Language Fundamentals > Data Types

Syntax

L = strlength(str)

Returns the length of each text in str.

Description

strlength counts characters per element of a string array, so strlength(["hello" "" "ab"]) is [5 0 2]. This differs from length and numel, which would report the number of strings in the array rather than the size of each string.

For a missing string the result is NaN.

Input arguments

str: String array, character vector, or cell array of character vectors.

Output arguments

L: Double array of the same size as str; for a character vector, a scalar.

Example

Per-string lengths

strlength(["hello" "" "ab"])
strlength('abc')
length(["hello" "" "ab"])

Output

ans = 1×3

     5     0     2
ans = 3
ans = 3
