isnumeric

Test whether the input is a numeric type.

Syntax

tf = isnumeric(A)

Description

Returns true when A’s element type is any numeric type — integer, floating-point, or complex. Returns false for strings, logicals, structs, cells, tables, and other non-numeric containers.

Applied elementwise for non-scalar inputs in script mode; scalar in Excel-compatible mode.

Examples

isnumeric(3.14)     % 1
isnumeric('hello')  % 0
isnumeric(true)     % 0  (logicals are not numeric)
