Hi,
I am currently trying myself on some human activity recognition on android. I used the "Human Activity Recognition Simulink Model for Smartphone Deployment" example as a starting point but as I wanted to do other activities and some more amndroid stuff I decided to only reuse some part of the 'slexHARAndroidExample' simulink i.e. the extractFeature block.
My problem is that I cannot simulate my model and if I use the embedded coder to deploy it, it classifys everything the same. Interesting is that it works correctly if I do it in Matlab step by step.
So if I run the following lines in Matlab directly it works fine:
feats = extractFeatures(X_Buff,Y_Buff,Z_Buff);
Act = predict(mdl,feats);
But if I want to simulate it by
with the same X_Buff,Y_Buff,Z_Buff in the workspace I get the following Error:
Index exceeds array dimensions. Index value 0 exceeds valid range [1-2049] of array f. Error in 'ClassME/extractFeatures' (line 133) ofpk = f(olocs); Error in 'ClassME/extractFeatures' (line 62) Error in 'ClassME/extractFeatures' (line 16)
although the code is the same.
Below is my simulink model where extractFeatures and predictActivity are taken from the example, although I trained the model for the predict block with diefferent data.
I am currently using Matlab version R2018b. Do you have any idea or starting point why it behaves like this?
