Question

我在Matlab＆＃34;神经网络模式识别＆＃34;中训练了一个神经网络。工具箱并从工具箱中生成.m函数。我还编写了自己的函数，它获取了一个包含带数据点作为输入的inf x 5矩阵的数据集，从工具箱中调用NN函数并返回一个具有识别模式和百分比值的向量。（输入矩阵包含应检测的模式）

因为我需要在Arduino上运行代码，所以我尝试使用Matlab编码器生成C ++代码，但它不起作用。首先，我得到一个警告：arrayfun不支持代码生成（调用os arrayfun位于工具箱生成的函数中）。之后，我将函数的输入定义为＆＃34;双倍（：7351 x 5）＆＃34; （它达到了7351，因为我的训练数据集很大）。现在编码器构建了一个MEX文件来检查运行时问题，并且发生了一些错误。

我不知道为什么目标构建日志是德语，因为Matlab的其余部分是英文的，但通常会丢失一些括号和分号，但为什么呢？如何在matrix.h或amlrt.h中删除括号???

一般情况下，可以从NN工具箱创建C ++代码，但为什么它在我的情况下不起作用？

我想在c ++中翻译的函数是：

function [ activity, percent ] = NeuralNetwork( Data )
%NN for recogniton of activitys standing, sitting, walking from Accelerometer data, relative error
%is returned in percent
%   input Data contains 5 columns. 1. col -> time; 2-4.col ->
%   x,y,z-Acceleration; 5.col -> activity
%   VAR activity contains 1 for walking, 2 for sitting and 3 for standing 


    Acceleration_data = Data(:,2:4);  %store acceleration data in a matrix
    Acceleration_data = Acceleration_data';     %NN input expects transposed matrix

    targets = Data(:,5);    %activity that should be detected from the NN
    targets = targets';     %output of NN is also transposed

    NNfit = myNeuralNetworkFunction(Acceleration_data); %call the trained NN 
    NNfit = round(NNfit);                             %output can be e.g. 0.998 -> round to 1
    activity=zeros(1,length(NNfit));                   %allocate memory for cpp-code


for i=1:length(NNfit)               %NNfit is a 3D matrix, after round one
    [val pos] = max(NNfit(:,i));    %element is 1 the other are 0 the number of 
                                    %the row represents the activity
    activity(i) = pos;              %vektor containing the activity
end

cnt=0;              %calc percent of correct recognized data points
for i=1:length(NNfit)
   if activity(i) == targets(i)
       cnt = cnt+1;         %amound of correct recognized data points
   end
end

percent = (cnt/length(targets))*100;   %calc percent

end
