TYPEOF Determine the Type of an Argument

Section: Inspection Functions

Usage

Returns a string describing the type of an array. The syntax for its use is
   y = typeof(x),

The returned string is one of

Example

The following piece of code demonstrates the output of the typeof command for each possible type. The first example is with a simple cell array.
--> typeof({1})

ans = 
cell

The next example uses the struct constructor to make a simple scalar struct.

--> typeof(struct('foo',3))

ans = 
struct

The next example uses a comparison between two scalar integers to generate a scalar logical type.

--> typeof(3>5)

ans = 
logical

For the integers, the typecast operations are used to generate the arguments.

--> typeof(uint8(3))

ans = 
uint8
--> typeof(int8(8))

ans = 
int8
--> typeof(uint16(3))

ans = 
uint16
--> typeof(int16(8))

ans = 
int16
--> typeof(uint32(3))

ans = 
uint32
--> typeof(int32(3))

ans = 
int32
--> typeof(uint64(3))

ans = 
uint64
--> typeof(int64(3))

ans = 
int64

Float, and double can be created using the suffixes.

--> typeof(1.0f)

ans = 
single
--> typeof(1.0D)

ans = 
double
--> typeof(1.0f+i)

ans = 
single
--> typeof(1.0D+2.0D*i)

ans = 
double
