Converting a SPICE subcircuit to Simscape component

 Hi everyone,

 
I have a serious problem, which I cannot solve myself.
Task: I want to convert a SPICE subcircuit to a Simscape component using the matlab syntax "subcircuit2ssc(filename,target)" The SPICE subcircuit are only related to Inductors and mutual inductors.
SPICE-model:
.subckt Ckt_model_series 1 2 3 4 5 6
L1 1 4 3.93e-09
L2 2 5 5.35e-09
L3 3 6 5.39e-09
K12 L1 L2 0.38
K13 L1 L3 0.45
K23 L2 L3 0.19
.ends Ckt_model_series
 
Problem: After converting I get the following message in the .ssc file:
% Users should manually implement the following SPICE commands in order to
% achieve a complete implementation:
% ckt_model_series: K12 l1 l2 0.38
% ckt_model_series: K13 l1 l3 0.45
% ckt_model_series: K23 l2 l3 0.19
This basically means all three inductor coupling are not taken into consideration. According to this link my syntax should be right.
Question: Where is my mistake and how can I manually implement the SPICE commands afterwards? I need this solution for even bigger circuits

Could you please confirm which release you are using?
 
Support for the coupling factor component was added in R2019a, I believe. If you have access to that release or later, it should just work for you.
 
If you don't have access to that release, then the best solution is to write the relevant equations for yourself. For this simple case, I can give you an example. Basically, it just involves writing out the differential equations. Note that L1, L2 and L3 are variables representing the currents through those inductors, so I'm just writing something like v1 = L1*i1.der + k12*sqrt(L1*L2)*i2.der + etc.

        node_5 = foundation.electrical.electrical; % node_5
        node_6 = foundation.electrical.electrical; % node_6
    end

    variables
        L1 = {value={0,'A'},priority=priority.none};
        L2 = {value={0,'A'},priority=priority.none};
        L3 = {value={0,'A'}

USING MACHINE LEARNING CLASSIFICATION ALGORITHMS FOR DETECTING SPAM AND NON-SPAM EMAILS

    ABSTRACT We know the increasing volume of unwanted volume of emails as spam. As per statistical analysis 40% of all messages are spam which about 15.4 billion email for every day and that cost web clients about $355 million every year. Spammers to use a few dubious techniques to defeat the filtering strategies like utilizing irregular sender addresses or potentially add irregular characters to the start or the finish of the message subject line. A particular calculation is at that point used to take in the order rules from these email messages. Machine learning has been contemplated and there are loads of calculations can be used in email filtering. To classify these mails as spam and non-spam mails implementation of machine learning algorithm  such as KNN, SVM, Bayesian classification  and ANN  to develop better filtering tool.   Contents ABSTRACT 2 1.

Why are Fourier series important? Are there any real life applications of Fourier series?

A  Fourier series  is a way of representing a periodic function as a (possibly infinite) sum of sine and cosine functions. It is analogous to a Taylor series, which represents functions as possibly infinite sums of monomial terms. A sawtooth wave represented by a successively larger sum of trigonometric terms. For functions that are not periodic, the Fourier series is replaced by the Fourier transform. For functions of two variables that are periodic in both variables, the trigonometric basis in the Fourier series is replaced by the spherical harmonics. The Fourier series, as well as its generalizations, are essential throughout the physical sciences since the trigonometric functions are eigenfunctions of the Laplacian, which appears in many physical equations. Real-life applications: Signal Processing . It may be the best application of Fourier analysis. Approximation Theory . We use Fourier series to write a function as a trigonometric polynomial. Control Theory . The F
