Pass Data to MATLAB from Python

Python Type to MATLAB Scalar Type Mapping

When you pass Python^® data as input arguments to MATLAB^® functions, the MATLAB Engine for Python converts the data into equivalent MATLAB data types.

Python Input Argument Type — Scalar Values Only	Resulting MATLAB Data Type
`float`	`double`
`complex`	Complex `double`
`int`	`int64`
`long` (Python 2.7 only)	`int64`
`float(nan)`	`NaN`
`float(inf)`	`Inf`
`bool`	`logical`
`str`	`char`
`unicode` (Python 2.7 only)	`char`
`dict`	Structure if all keys are strings not supported otherwise

Python Container to MATLAB Array Type Mapping

Python Input Argument Type — Container	Resulting MATLAB Data Type
`matlab` numeric array object (see MATLAB Arrays as Python Variables)	Numeric array
`bytearray`	`uint8` array
`bytes` (Python 3.x) `bytes` (Python 2.7)	`uint8` array `char` array
`list`	Cell array
`set`	Cell array
`tuple`	Cell array

Unsupported Python Types

The MATLAB Engine API does not support these Python types.

array.array (use MATLAB numeric array objects instead; see MATLAB Arrays as Python Variables)
None
module.type object
