int8 - Class: categorical

Convert categorical array to signed 8-bit integer array

Syntax

Description

B = int8(A) converts the categorical array A to a signed 8-bit integer array. Each element of B contains the internal categorical level code for the corresponding element of A.

Undefined elements of A are assigned the value 0 in B. If A contains more than intmax('int8') levels, the internal codes will saturate to intmax('int8') when cast to int8.
