out =
double (obj)
¶Convert to double array, by getting the underlying code values.
Converts obj to a string array. The doubles will be the
underlying numeric code values of obj, or NaN
for
undefined values.
The numeric code values of two different categorical arrays do *not* necessarily correspond to the same string values, and can *not* be meaningfully compared for equality or ordering.
Returns a double
array the same size as obj.
