Convert Python list Type to MATLAB double
显示 更早的评论
Hello All,
I would like to convert the python list type to matlab double.
I have tried the following,
First approach
out = func.getValues() %python function gives a list of [1,2,...n]
out = cell(out(1:end-1));
out = cellfun(@double,out); %outputs type double
Second approach
out = func.getValues() %python function gives a list of [1,2,...n]
out = func.convlisttoarray(out) %python function imports numpy and converts list to array using numpy.array()
out_double = double(out); % outputs type double
Although the length of the list is 1x150, in both the approaches, Matlab is taking a lot of computation time and the system hangs for a while. This is wierd to me, as a couple of days earlier everything worked fine and it could solve the problem in milli seconds.
Could anyone of you please help me with a faster approach to convert the python list to matlab double?
I am using Matlab 2019b.
Thank you in advance.
Cheers,
Sai Krishna

q = py.list({1,2,3})
cq = cell(q)
[cq{:}]

Where does "py." come from?
I get a Not defined Error
Do you have python installed and configured? I.e. what's the output of
pyenv
It should not be empty.

I'm also using 2019b and cannot figure out how to convert python lists to matlab array.
q = py.list({1,2,3})
cq = cell(q) %errors out in 2019b . . .
Error using cell
Conversion to cell from py.list is not possible.
Later versions of Matlab support this, but not 2019b and below, which I (and my workgroup) am stuck using.
