Hello,
I have converted the Matlab code bb.m into Scilab and the calculations are all
fine. Verified the results in Octave. However, the beachball fill plot is not
working:

A workaround finds the unique segments from the plot:

Hi all,
After a lot of trial and error, I have managed to get a set of functions to
compute the approximations of Riemann's Zeta for negative and positive real
values; values of n > 1e6 seem to give better results:
function zs=zeta_s(z, n)

As a test, I increased the value n (iterations) and that forced it to
converge on the value 150999.
Sounds like I need a test of convergence.

This is the simplest option, based on primes(35):

Hello all
I am looking to use the sciNetCDF module to work with GMT grid files
but have some issues.
Reading a GMT grid is not a problem as far as I can tell, so the
following does read the file (and z variable), storing the values in
the grav array:
source = fullfile('Q:\geophys\Gz.grd')
grav
Hello
A quick query. How would one define the Hilbert transform of a grid
for X and Y directions; looking for two solutions Hx and Hy (for the
real values).
Thanks

Hello,
I have a quick query realted to the change from 5.4.1 to 5.5.2 (and
6), related to a vector^scalar operation. The basic code runs and
plots the curves as needed but generates warnings on running:
clear()
clc()
functions_library = lib('C:\geophys\Lester\SCILAB_work\Functions');
//Finds the
lamda_k = lamda*1000;

Hello,
I am trying to create a loop to plot three curves from an input variable (Te):
clear()
rho_m = 3330;
rho_fill = 2400;
g = 9.81;
Pb = -1.5e12;
v = 0.25;
E = 1e11;
x=linspace(0,200,41);
for Te = 5000:25000:1 // start:end:step to make 5000, 15000, 25000
D = E*Te .^3/(12*(1-v^2));
Thanks for that pointer.
The plot works but only does Te=25 in this case
for Te = 5000:1:25000 // start: step: end
D = E*Te .^3/(12*(1-v^2));
lamda = ((rho_m-rho_fill)*g ./(4*D)).^0.25;
lamda_k = lamda*1000;
flex =
ly after one has cached module list.
Thanks

As you say Antoine, room for improvement in terms of installing
offline for sure.

Just installed v5.5.2 and get the same issue when trying to install a
module manually, error 21 at line 170 of atomsInstall
Scilab is installed in Program Files on Windows, and so I am guessing
that it might be a permissions issue for a work machine?

Hello,
I currently have v5.4.1 of Scilab, and have to install modules manually.
I am trying to install apifun (as quite a few modules use it), but get
this error
-->atomsInstall('c:\ss20-work\scilab\apifun_0.4.2-3.bin.zip')
!--error 21
Invalid index.
