ISA ISA Test Type of Variable

Usage

Tests the type of a variable.  The syntax for its
use is

   y = isa(x,type)

where x is the variable to test, and type is
the type.  Supported built-in types are
  -  'cell' for cell-arrays

  -  'struct' for structure-arrays

  -  'logical' for logical arrays

  -  'uint8' for unsigned 8-bit integers

  -  'int8' for signed 8-bit integers

  -  'uint16' for unsigned 16-bit integers

  -  'int16' for signed 16-bit integers

  -  'uint32' for unsigned 32-bit integers

  -  'int32' for signed 32-bit integers

  -  'uint64' for unsigned 64-bit integers

  -  'int64' for signed 64-bit integers

  -  'single' for 32-bit floating point numbers

  -  'double' for 64-bit floating point numbers

  -  'char' for string arrays

If the argument is a user-defined type (via the class function), then
the name of that class is returned.
