How to save or convert a simulink model to csv file

Hi all,I have a tank system in simulink and would like to save or convert it to a csv file.Does anyone know how this can be done?

A .csv file is typically a text-file with comma-separated numerical values - how can a Simulink model be represented simply in terms of numerical values? AFAIK, such a conversion is not possible.

Thanks Govind for your answer.What would you advice in this situation,i want to communicate with labview via shared memory as i dont have the instrument control toolbox to communicate with labview via TCP/IP.In what format can i save the file in a particular location for labview to be able to read it?Dont know if you understand what i am trying to do

Are you trying to pass the output of a Simulink model into LabView, such as a time series of simulated position and velocity? If so then you can use a To Workspace block in your Simulink model to pass the time series out of Simulink and into Matlab's workspace, then in Matlab you could save the variable to a CSV file using a Matlab utility such as csvwrite. Then you could read the resulting csv file into LabView. There are other ways to go from [Simulink time series] to [saved csv file]; this is one example.

Alternatively you can save the Simulink output to a *.mat file using the 'To File' block (http://www.mathworks.com/help/toolbox/simulink/slref/tofile.html). Perhaps there is a LabView utility to read a mat file into LabView. Or, you could add a function block to your Matlab model that uses fprintf or csvwrite to export the data, but see Fangjun's warning about it here,

Here is a thread on reading a mat file into Labview,

Since I am not a Labview user, you would want to follow up in that forum with any followup Labview questions.

Hi KE,thanks for you answer to my question about converting a simulink model into a csv file.What i really want to do is that,i have a tank model in simulink and the user interface of this tank model will be in Labview.Since i dont have the instrument control toolbox to communicate via TCP/IP i want a situation where i can write the input and output of the tank to a file,Labview will read from that file and display that on the user interface.Labview too will also write to a file and simulink will read from that file.Do you think this can be done?Thanks and hope you understand what i am trying to say.Dont want to go through Matlab
