[TRNSYS-users] How to call all inputs at the same time in MATLAB?

Dear Reza:


If the inputs from TRNSYS are independent of the outputs from MATLAB, one
solution could be this one:

Run the case in TRNSYS and export the results (e.g. T_ambient) to a xls

Load the data with MATLAB and make the mathematical process. 

Write the results  from Matlab in another xls file. 


If you need to postprocess these data in TRNSYS, you can read them from the
xls file and run again the project.


Sure there is a better way to do it, but this manner is quite simple and
fast, and you do not need to change your case a lot.

Dear all TRNSYS users and Happy Spring;

If I use Matlab code alone, I can load my whole data e.g T_ambient (every
second) as my input data (6000) using "Load" command; and since I use some
partial difference equations, I interpolate these 6000 data base on very
small time step (dt=0.01 second). Thereafter, Matlab processes these 600,000
data in “for loop” and produces the outputs at the end of “for loop”.

My problems is that: If I link Matlab and TRNSYS together: 

base on my initial understanding from Trnsys’s example, Trnsys call Only
“one data” in each time step and process that only input to produce only one
output. I want Trnsys to call all my data (6000) (like load command in
Matlab) and pass these 6000 data to Matlab, and get 6000 output data from
Matlab after mathematical process. Exactly like the command "Load" in Matlab
to call my all inputs.


I am looking your favorable email very soon :)

Sincerely Yours
