Hi Stephane, At the moment I am just trying to understand how Scilab works with triple integration of f(x,y,z) with limits for xyz. Lester -- Sent from: http://mailinglists.scilab.org/Scilab-users-Mailing-Lists-Archives-f2602246.html ___ users

Hello all, An update on a solution. Following e-mail correspondence with a fellow Scilab user (Javier Domingo), he has worked out a general solution to vectorising the X,Y,Z arrays for the tetrahedrons required by int3d. So taking this part of the code and adding a call to int3d within a function

Hello, I am also in favour of including this function in Scilab, with an “improved” name. However, as far as I know, an inset has very frequently its own pair of axes, as opposed to a ticks-switching in (only one of) the axes. Thus, I would not recommend a name with “inset” and reserve it for

Hi Lester, If I understand well, you are only interested by integrating on [x1,x2] x [y1,y2] x [z1,z2] and not a general volume, that's it ? S. Le 02/04/2021 à 11:53, arctica1963 a écrit : Hello all, An update on a solution. Following e-mail correspondence with a fellow Scilab user (Javier

Hello Samuel, hello all, First thanks for the request for inclusion, that’s always good to have more features into Scilab itself. However, I have a few remarks regarding this function. 1. The function name plotplots() does not seem well known nor easy to find ; after a few research I
