How to call a variable from aspen to matlab without using EXCEL when variable has no attributes in aspen.

I have tried calling PSD(particle size distibution ) variable from aspen to matlab but everytime it gives 1 as value and not the set of data like an array. Also, since the PSD variable does not have an attribute to it can it be called through matlab??

Hi Gopi,

As per my understanding, you basically want to exchange the data between ASPEN and MATLAB without using Excel.

There is no out-of-the-box function present in MATLAB that directly does the same, but you can utilize the COM interface to exchange the data. In order to do so, you first need to configure ASPEN to allow COM access, and then you can utilize the "actxserver" function of MATLAB to create a COM server, followed by utilizing it for data fetching.

You can refer to the below file exchange link, where a user has given a sample code for the same:

You can also refer to the below video, where they are doing this step-wise:

I hope this will help you to proceed ahead with your workflow!
