Hello Friends,

I need some help as regards predicted values from an LSTM neural netwrok that I designed. See the attached picture of the main code for the LSTM.
After training , the predicted values are always different from the previous simulation.
In the training options, I tried to set the BiasInitializer to zeros and the WeightsInitializer as well to ones but still the changes in predicted values always occur.

I will be glad if someone can guide me on this point.Hello Friends,

This should be easy… Data comes in from a serial device consisting of a character and a number (time in msec) and I want to insert it into a table on screen.
I’ve got my serial callback working (after much effort) and I thought the next step would be easier. I have created a uitable that is displayed on the screen. Empty at first, called ResultsTable and thus referred to as app.ResultsTable with 2 columns named ‘Event’ and ‘Time’. Everything else about the table is defaulted.
The app.ResultsTable.Data is initially [ ] as expected and as each bit of info comes in I want to add it to the table. Serial callback parsed the input into PType (a character) and PTime (uint32) so why does
app.ResultsTable.Data(app.NextTrial,’Event’) = char(PType);
app.ResultsTable.Data(app.NextTrial,’Time’) = PData;
Give me multiple columns where the number of columns is the ascii value of the character? If PType is ‘A’ I get 64 zeros and then a 65. I’ve tried various combinations of [ PType PData ] ( etc.) { another attempt }. All kinds of complicated merging of multiple tables is described in help but not simply putting new data into a new table within App Designer code (which has to be different than MatLab of course)
And after I get that first row in, I sure hope I can keep adding rows (app.NextTrial is the row index of course) for as long as I have enough memory (maybe 1000 rows?), that I can later export to an excel file or .CSV.

is it posssible to get them from matlab with patten func or other wayi work withh pattern function in matlab but i can get the result and only get err i dont know i can use it or not?
i get text from cst like it for 2D

in above table i only use first three column which means i like to have pattern in constant phi with various theta
in cst i get this pattern and i want get it in matlab
