Andrew on 15 Nov Vote 2. Accepted Answer: Sean de Wolski. The input argument A can have any data type. If A is an object, then isa returns 1 if dataType is either the class of A or a superclass of A. If A is an object, then isa returns 1 if the class of A , or any superclass of A , belongs to the specified category. Create a numeric variable and determine if its data type is double.

Create an array of bit integers and determine if its data type is int Determine if the data type of A is char. Create an array whose data type is uint8. Determine if the array has a data type that belongs to the integer category. Determine if the data type of A belongs to the float category. Data type, specified as a character vector or string scalar. Another related function is whos. It will list all sorts of information dimensions, byte size, type for the variables in a given workspace.

Be careful when using the isa function. This will be true if your object is of the specified type or one of its subclasses.

You have to use strcmp with the class function to test if the object is specifically that type and not a subclass. Since nobody mentioned it, MATLAB also has the metaclass function, which returns an object with various bits of information about the passed-in entity. These meta. We can see that class someObj is equivalent to the Name field of the result of metaclass someObj.

To get more details about variables you can use whos command or whos function. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Explanation: The content of the variable can be edited using command or can be edited from the variable editor.

Apart from editing, the other operations such as deleting, duplicating, copying, resizing, or reshaping the variable can be done in the workspace. Numeric variables are captured in the form of bit 8-byte double-precision floating-point value automatically. Matlab supports variable arrays that of the singed integer data type. Logical value can be used in Matlab programming in the form of a variable.

But Complex values and NaNs are not supported for logical value conversion and throws conversion error. Any non-zero element gets converted as logical 1 i. Boolean true and 0 gets converted as logical 0 i. Boolean false.
