call python function using matlab function and matlab system block -凯发k8网页登录

use python functions in simulink model

this model contains a random number generator that outputs a 1x5 double containing numbers from 0 to 1, a matlab function and a matlab system block that sorts the numbers, and a manual switch that leads to a display block.

the matlab function block calls the py.sorted function from python and outputs a 1x5 double sorted list, as seen below in the code snippet.

function y = fcn(u)
    % sort values of 'u'
    coder.extrinsic('py.sorted');
    ytmp = py.sorted(u);
end

the matlab system block calls the py.sorted function as part of and outputs a 1x5 double sorted list as seen below in the code snippet.

function y = stepimpl(~,u)
    % implement algorithm. calculate y as a function of input u and
    % discrete states.
    y = py.sorted(u);
    y = cellfun(@double,cell(y));
end

running this model using the matlab function block or matlab system block yields a sorted list of the numbers generated in the random number generator block. an example of this can be seen below.
