If a Python function expects a specific Python multidimensional array type such asnumpy.ndarray, then MATLAB displays a message with tips about how to proceed. If the problem might be due to passing a matrix or a multidimensional array as an argument, then do the following. Check the documenta...

For now, I chose to relax this condition as this function (is_bounds_page()) is only being used in string decoders (narrower scope) and the described problem is only being seen in string cols. Contributor etseidl Nov 14, 2024 This makes me nervous. So in the normal case, won't th...

Create a Python object of that type in MATLAB and pass that to the Python function. For example, suppose that the following code returns an error. a = [1 2; 3 4]; py.pyfunc(a) If the documentation ofpyfuncspecifies that the expected type isnumpy.ndarray, then try this conversion: ...
