The reason I ask is that I have an application that (among other things) calls a MATLAB .NET component whenever data is written into a specific file. The component reads the file and creates an image out of the data contained within. This works fine.

However when I am using the underlying application to additionally process a “significant” amount of data and display the processed data in table, the call to MATLAB throws an out of memory exception, but only when I am processing this large amount of data.

Is this not an indication that the MATLAB process called will rely on the available memory of the application? I guess I just don’t understand how the MATLAB memory works when being called from a .NET standpoint.

(I should also note that I call clear all before every call to the MATLAB function in an attempt to “start from scratch”, but it fails regardless)

    COM components built by Matlab Builder NE are in-process COM servers. This means that they are DLLs which are loaded into your application memory space. This means that the MCR, which is a kind of Matlab-Virtual-Machine is in your memory space.

    I believe that .NET components should behave exactly the same.
