Class: categorical

Convert categorical array to unsigned 32-bit integers

The nominal and ordinal array data types might be removed in a future release. To represent ordered and unordered discrete, nonnumeric data, use the MATLAB® categorical data type instead.


B = uint32(A)


B = uint32(A) converts the categorical array A to unsigned 32-bit integers. 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.
