Convert Text to Numeric Values

Convert text to arrays of numeric values. Text can represent floating-point values, dates and times, and hexadecimal and binary numbers. If text represents dates and times, then you can convert the text to datetime or duration values.

Convert Numeric Values to Text

Convert numeric values to text. Text can represent floating-point values, either with or without exponential notation, or hexadecimal or binary digits. Use these conversions to add numbers to text such as plot labels or titles.

Unicode and ASCII Values

MATLAB^® stores all characters as Unicode characters. Both strings and character vectors use the same encoding. You can convert characters to their Unicode code values, and numbers to characters.

Hexadecimal and Binary Values

Specify hexadecimal and binary values either as literals or as text. Hexadecimal and binary literals are stored as integers. You can convert text representing hexadecimal and binary values to numbers, and numbers to text representations.

Convert Between Datetime Arrays, Numbers, and Text

While datetime is the recommended data type for representing points in time, you might need to work with dates and time stored as date strings, date vectors, and serial date numbers.

Convert Text in Table Variables to Categorical

This example shows how to convert a variable in a table from a cell array of character vectors to a categorical array.

Valid Combinations of Unlike Classes

If you include elements of unlike classes in a matrix, MATLAB converts some elements so that all elements of the resulting matrix are of the same type. Data type conversion is done with respect to a preset precedence of classes.
