# clear

Clearing variables

### clear('variables')

• All of the above statements clear all user-defined variables in the workspace, and free the memory spaces occupied by them.
• NOTE: Command syntax, e.g., clear all, is not supported.

### clear(v1, v2, v3, ..., vn)

• v1, v2, ..., vn are character arrays of variable names. This statement clears the listed variables in the workspace, and free the memory spaces occupied by them.
• All input arguments should be non-empty arrays.

Example 1:

a = 1
b = 2
clear('a', 'b')

a =
1.000

b =
2.000

Variable "a" cleared.

Variable "b" cleared.
