Aufrufen von Python aus MATLAB heraus
Sie können auf Python-Bibliotheken direkt aus MATLAB heraus zugreifen, indem Sie das Präfix py. vor den Python-Namen setzen. Siehe Access Python Modules from MATLAB. Beispiel:
py.list({'This','is a','list'}) % Call built-in function list
py.textwrap.wrap('This is a string') % Call wrap function in module textwrappyrun oder pyrunfile. Beispiel:pyrun("l = ['A','new','list']") % Call list in Python interpreterWeitere Informationen dazu, wie Sie stattdessen MATLAB-Funktionen aus Python Anwendungen heraus aufrufen, erhalten Sie unter Aufrufen von MATLAB aus Python heraus.

- Pass Data Between MATLAB and Python from MATLAB
The Python interface converts MATLAB data into compatible Python data types. - Access Elements in Python Container Types
A Python container is typically a sequence type (listortuple) or a mapping type (dict). - Use Python Datetime Types in MATLAB
MATLAB supports conversions between MATLABdatetimevalues and Pythondatetimeor NumPydatetime64values. - Use Python Duration Types in MATLAB
MATLAB supports conversions between MATLABdurationvalues and Pythontimedeltaor NumPytimedelta64values. - Pass Python Function to Python map Function
This example shows how to display the length of each word in a list.
