How to use mathscript node in server side with the parameter from the client side

[kkccoo]

I tried to develop a server/client system with some algorithms written in matlab. So I included a mathscript node on the server side. The client will send the parameter to the server. According to these parameters, the sever will call the matlab functions to do some computings and then send the results back to the client. The server has to wait for all parameters received before the computings. How do I know this since I only connect the parameter variables to the inputs of mathscript node on the server. The sever cannot know whethere these parameters are the new ones or old ones since the client may send parameters multiple times?

It seems to me you have two perfectly good options to start with. You could send all possible parameters in a single packet from the client to the server. This could be in the form of a cluster or an array of values. If by server/client you mean you are sending data over the network, then you could flatten this data to string before sending and unflatten it on the other side. Since all parameters come in one packet, you know all the data is valid every time you send data.

The other option is to send the parameters individually, but include some extra information such as a timestamp or iteration count. The server keeps reading and storing parameter values until a packet arrives with the next timestamp. Alternatively, you could include some information such as an end-of-parameter-list boolean that is sent with every parameter. It would be false until the last parameter packet.

Give it a thought. There are lots of solutions.
