➺ A valid variable name starts with a letter, followed by letters, digits, or underscores. ... The maximum length of a variable name is the value that the namelengthmax command returns. You cannot define variables with the same names as MATLAB keywords, such as if or end .

➺A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.

Answer 2

The following is a valid variable name​

• The name of the variable must not be a keyword, it cannot start with a digit, and it must not contain a special symbol.
• The underscore character or a letter must come first in a variable name. A number cannot come first in a variable name. Only underscores (A-z, 0-9, and _) and alphanumeric characters are permitted in variable names. Names of variables are case-sensitive (age, Age and AGE are three different variables).
• A variable may contain letters, numbers, and underscores. A variable name can only begin with an alphabetic character or an underscore. It cannot be the first digit. The variable name cannot contain any spaces.
• You can give symbolic variables names that have meaning. Variables with descriptive names, like PAY RAISE, make CLISTs simple to read and update since they describe their contents. The ampersand (&), which instructs the CLIST to utilise the variable's value, is not a part of a variable name.
