Hi I am new to scilab and don’t have much mathematical background.
I have been following code for another example and am being shown error 10000 for the following code:
function [z]=f(x,y)
z=0.026*(1.0-(y/ym))*y;
endfunction;
ym=12000;
x0=1950;y0=2555;xn=5;h=10;
x=[x0:h:xn];
y=ode("rk",y0,x0,x,f);
disp("x y")
disp("--------")
disp([x'y']);
function z=fe(x)
z=ym/(1-(1-ym/y0)*e^(-k*(t-t0)));
endfunction;
xe=(x0:h/10:xn);
n=length(xe)
for i=1:n
ye(i)=fe(xe(i));
end;
plot (x,y,'ro',xe, ye,'-b');legend ('rk4','Exact',3);
xtitle('solving dy/dx=k(1-y/ym)y','x','y');
I have worked through several other error messages. I am lost and don’t know if the problem is in the code or the way I set up the problem. The following is the current error message:
!--error 10000
plot: Wrong size for input argument #2: A non empty matrix expected.
at line 57 of function checkXYPair called by :
at line 235 of function plot called by :
plot (x,y,'ro',xe, ye,'-b');legend ('rk4','Exact',3);
at line 25 of exec file called by :
I would appreciate any help.
Thanks
I am new to Scilab, but I do have MatLab and Octave experience. I’m just starting to write custom functions and when I try to load them into Scilab, I get the following error.
!--error 10000
listvarinfile: Wrong variable type (1.686D+08) found in '<pathname>\test.sci'. File may be wrong or corrupted.
at line 50 of function listvarFunction called by :
at line 29 of function listvarinfile called by :
at line 949 of function %_sodload called by :
<pathname>\test.sci'
In this case the test file was pretty simple:
function [x]=test(y)
x = y*y;
endfunction
saved with the .sci extension.
The function was loaded from the IDE by right clicking on the file and choosing the Load into Scilab option.
I had more complex examples but decided to write this since they were not loading either.
Thanks for your help.

Unlike in Matlab, in scilab you need run the function.
Just run the function first and then call it in the console .
test(4)
ans =
16.

Just as user2240469 said, but you can do this in the console. See also the documentation of exec.
// Use -1 as mode to prevent printing everything in the console
-->exec('test.sci',-1)
-->test(4)
ans =
16.

Please note that the recommended version of Scilab is 2023.1.0. This page might be outdated.
See the recommended documentation of this function
Scilab Help >> Scilab > Error handling > error
Calling Sequence
error(message) error(message, n) error(n) error(n, message) error(n, pos)
Arguments
- message
-
a string or a vector of strings. The error message to be displayed.
- n
-
an integer. The number associated with the error message.
- pos
-
an integer. A parameter for the error message.
Description
error function allows to issue an error message and to
handle the error. By default error stops the current
execution and resume to the prompt level. This default can be changed
using the errcatch or execstr(...,'errcatch') functions.
error(message) prints the character string contained in
message. The number associated with the error message is
10000
error(message,n) prints the character string contained in
message. The number associated with the error message is
given by n. This number should be greater than 10000.
error(n) prints the predefined error message associated with
the error number n.
Some predefined error messages require a parameter (see
error_table). In this case the pos
argument must be used error(n,pos) to give the parameter
value. In the other cases the pos argument is ignored.
See error_table for a list of error messages and the
associated error numbers.
Examples
error('my error message') error(43) error(52, 3) error(10001, ['A'; 'multi';'line';'error';'message']) lasterror()

Я столкнулся с проблемой при загрузке набора инструментов SIVP в консоли Scilab. Я использую scilab 5.5.0. Я установил libtiff4. Я получаю следующую ошибку. Может кто-нибудь, пожалуйста, помогите?

У меня такая же проблема. Я использую Fedora 20. Перейдите в папку lib и проверьте, есть ли у вас libtiff.so.4, у вас, вероятно, нет этого файла, иначе вы не получили бы эту ошибку. Тем не менее, вы можете иметь libtiff.so.5 или.3. Если у вас более старая версия, просто установите.4, установив openCV. Если у вас есть.5, то вам нужно создать символическую ссылку, как sudo -c 'ln -s libtiff.so.5 libtiff.so.4
Это решает проблему в Linux.

У тебя есть либтиф?
Если нет, и вы используете Ubuntu
sudo apt-get install libtiff4

Hi All,
I’m new(bie) to Scilab (4.1.2), then sorry if my problem is too
simple. But I’m trying to compile one example of the function
«addmenu». The result was

\n»»,name,*entry+1);’
—> ‘ else’

+1,*win);’
—> ‘}’];

What I should do to fix this error? Thanks.
