How to get the type of a variable in MATLAB?

MATLAB是否有一个函数/运算符指示变量的类型（类似于JavaScript中的typeof运算符）？

使用class功能

>> b = 2
b =
     2
>> a = 'Hi'
a =
Hi
>> class(b)
ans =
double
>> class(a)
ans =
char

---

class() function is the equivalent of typeof()

You can also use isa() to check if a variable is of a particular type. If you want to be even more specific, you can use ischar() , isfloat() , iscell() , etc.

Another related function is whos . It will list all sorts of information (dimensions, byte size, type) for the variables in a given workspace.

>> a = [0 0 7];
>> whos a
  Name      Size            Bytes  Class     Attributes

  a         1x3                24  double              

>> b = 'James Bond';
>> whos b
  Name      Size            Bytes  Class    Attributes

  b         1x10               20  char
