Greetings
I’m using i.gensigset and I realized that, in a few variavbles, memory is not being released. and those are:
indx = G_alloc_ivector(nbands);
y = G_alloc_matrix(nbands, nbands);
col = G_alloc_vector(nbands);

What specific functions, from GRASS APIm can I use to release allocated memory for those?

Thanks
Pedro

None, because these are static variables [1], memory is allocated only
once and automatically released when the program terminates. Why do
you think the allocated memory should be explicitly released?
