Custom module - add 2D array variable

Hello,

I am currently creating a custom module with Audio Weaver, and I need to add a 2D array/matrix variable for my module.

According to the manual, the variables can be either scalar or array (which I managed to do) but I was wondering if there might be a way to do the same with 2D array.

Thanks for your answer,

Best,

Quentin

Hello Quentin,

Yes Audio Weaver Variables can support 2D arrays. Section 3.7, starting on page 59 of our Audio Weaver Module Developer's Guide goes over the add_array.m function, which you can specify a 2D array in the data argument.

Thanks,

Kevin

Hi Kevin,

Thanks for your answer. So if I understood well when creating a 2D array in Matlab, the memory allocation of the array in the ModModuleLib.c file (i.e for the target or native mode implementation) will be a 1D array, and elements are accessed columns by columns?

For instance M[i][j] will correspond to M[i*sizeJ + j], is that correct ?
