[Scilab-users] Numderivative and integrate

[Rafael Guerra]

Hi Hermes,



Regarding your question "the FourMatDiff function could be improved. Is there any function in Scilab to create band Matrices?",

please note that following code:


M = toeplitz([0  -2/3  1/12  zeros(1,n-5)  -1/12  2/3]);
M = tril(M) - triu(M);



produces the same results for n >=5 as your function:  FourMatDiff2(n)



Regards,

Rafael
