[scilab-Users] Using a cell entry to access part of a matrix

[Iai Masafumi ax]

Thanks for your reply. I wanted to use a cell array to manage a lot of
variable in my code which is more complicated.

I guess I have to put my question in a different way:

After running the code below, type(II(1)) returns 17 while type(ii)
returns 1. According to the help, 1 means "real or complex constant
matrix". 17 means "matrix oriented typed list (mlist)". How do I convert
II(1) into a "real or complex constant matrix"?


I expected II(1) would return a matrix essentially identical as ii
because I stored ii into the first entry of a cell array, II, by letting
II.entries(1)=ii. But obviously what I expected was not the case.
