Description
This page gives the table of the predefined error messages, and
their associated error number. Some of these error messages are used by
Scilab itself for parser errors or specific builtin errors. Some others
are of a more general use and can be used in Scilab functions. The starred
ones are those for which the syntax error(n,pos) is
handled.

Description
This page gives a non-exhaustive list of the main standard predefined error messages
used in Scilab itself. These messages can be used in external codes as well.
Whatever is the current Scilab session language, the english version of a message is used
as message identifier by the gettext() translation system.
The listed messages are used in Scilab itself.
 |
Please avoid using double-quotes » inside messages: single quotes ‘ must be used |
A message may include some tags starting with the «%» symbol. These tags follow
a C-like syntax (see printf() conversion rules).
They aim to be replaced with custom contents, in order to customize the standard
with local data, thanks to msprintf. To include a true
«%» character in such a message, use «%%».
Standard messages must start with «%s» and end with «\n». The heading «%s» will be
replaced with the name of the function in which the error occurs.

"%s: Wrong number of input arguments.\n" "%s: Wrong number of input arguments: %d expected.\n" "%s: Wrong number of input arguments: %d or %d expected.\n" "%s: Wrong number of input arguments: %d to %d expected.\n" "%s: Wrong number of input arguments: At least %d expected.\n" "%s: Wrong number of input arguments: At most %d expected.\n"
Ouput arguments:
"%s: Wrong number of output arguments: %d expected.\n" "%s: Wrong number of output arguments: %d to %d expected.\n"

Wrong encoding:
"%s: Argument #%d: Sparse matrix expected.\n" "%s: Argument #%d: Dense matrix expected.\n"
Checking container’s dimension and sizes
Dimensions / sizes / shape of the container:
- «array» applies to Cells and Structures
- «Scalar», «Row», «Column» apply to matrices as well as to other arrays
(Cells and Structures)
"%s: Argument #%d: Non-empty matrix expected.\n" "%s: Argument #%d: Empty matrix expected.\n" "%s: Argument #%d: Scalar (1 element) expected.\n" "%s: Argument #%d: Row expected.\n" "%s: Argument #%d: Column expected.\n" "%s: Argument #%d: Vector expected.\n" "%s: Argument #%d: Row with %d elements expected.\n" "%s: Argument #%d: Column with %d elements expected.\n" "%s: Argument #%d: Vector with %d elements expected.\n" "%s: Argument #%d: Matrix expected.\n" "%s: Argument #%d: Square matrix expected.\n" "%s: Argument #%d: %d-by-%d matrix expected.\n" "%s: Argument #%d: Matrix with %d rows expected.\n" "%s: Argument #%d: Matrix with %d columns expected.\n" "%s: Argument #%d: Matrix with %s rows expected.\n" // %s is more general ; it could be used for a range "%s: Argument #%d: Matrix with %s columns expected.\n" // idem "%s: Argument #%d: 2D-array expected.\n" "%s: Argument #%d: Hypermatrix expected.\n" "%s: Argument #%d: %dD hypermatrix expected.\n" "%s: Argument #%d: %dD array expected.\n" "%s: Argument #%d: %d-element list expected.\n" "%s: Argument #%d: List of %d to %d elements expected.\n" "%s: Argument #%d: %s expected.\n" "%s: Implicit size not supported.\n" "%s: Hypermatrix not supported.\n"
Strings
"%s: Argument #%d: string length %s %d characters expected.\n" // '='|'>'|'>='|'<' ...etc

"%s: Argument #%d: The %s handle is no longer valid.\n" // Graphic, XML, lu etc handles
"%s: Argument #%d: Wrong color specification.\n"
Note that the error message for intervals is special: any type of interval like
[#, #], (#, #], [#, #), (#, #) (-oo, #], [#, oo), etc can be conveniently specified
within the same generic message. Bounds formatting and replacement must be performed
with msprintf(..)
Inter-Arguments constrains checking:

Dynamical systems
"%s: Argument #%d: Transfer matrix expected.\n" "%s: Argument #%d: In state space form expected.\n" "%s: Argument #%d: In continuous time expected.\n" "%s: Argument #%d: In discrete time expected.\n" "%s: Argument #%d: SISO expected.\n" "%s: Argument #%d: Undefined time domain.\n" "%s: Argument #%d: Invalid state space representation.\n" "%s: Argument #%d: A system in state space or transfer matrix form expected.\n"

Хотя инструкция не рекомендует задавать вопросы. Моя тема в форуме это всё-таки вопрос.
Суть дела в следующем. Опущу физику задачи. Решается конечная последовательность квадратных уравнений, коэффициенты которых определяются из рекуррентных соотношений. Для каждого уравнения вычисляется также из рекуррентных соотношений область допустимых значений. Для каждой пары корней выбирается один, соответствующий ОДЗ. Осуществляется это в цикле с помощью двух операторов if. Выглядит это так
A3 = zeros(1,q)
for i = 1:q
if (D1(1,i)>AN(i))and(D1(1,i) < AH(i)) then A3(1,i) = D1(1,i)
end
if (D1(2,i)>AN(i))and(D1(2,i)<AH(2,i)) then A3(1,i) = D1(2,i)
end
end
На консоле появляется сообщение
if (D1(1,i) > AN(i))and(D1(1,i) < AH(i)) then A3(1,i) = D1(1,i)
!—error 144
Операция для заданных операндов не определена.
отметьте или определите функцию %s_2_s как перегружаемую.
Что я делал:
1. Проверил распечатыванием типы переменных и их размерности;
2. Упростил логическую конструкцию до одного условия;
3. Проверил размерности массивов;
4 Уменьшил размерность массивов до 2 и соответственно в цикле количество итераций уменьшил до 2.
Всякий раз, когда выполнение программы подходило к if, появлялось сообщение, приведённое выше.
Установил я 5-ую версию scilab. Возможно это внутренние какие-то проблемы у программной среды? Надеюсь, кто-нибудь сталкивался с такими вещами. С уважением Станислав
пятница, 24 июля 2020
Всем доброго времени суток! Кто нибудь может объяснить, почему в цикле при появлении оператора if появляется сообщение кода ошибки 144 «Операция для заданных операндов не определена. отметьте или определите функцию %s_1_s как перегружаемую.»
scilab, ошибка, функция, цикл
почему то выдает ошибку, хотя делал по книжке
решение системы линейных алгебраических уравнений
x1 − 2x2 + 3×3 − 2×4 = −6
x1 + x2 − 2×3 − 3×4 = −8
3×1 − 2×2 − x3 + 2×4 = 4
2×1 + 3×2 + 2×3 + x4 = 8
делал через фаил сценарий,
—>exec(’C:\Program Files (x86)\scilab-5.4.1\111.sce’); disp(’exec done’);
выдает !—error 2
Неправильный множитель. подскажите пожалуйста в чем ошибка
A=[1 -1 3 -2;1 1 -2 -3;3 -2 -1 2;2 3 2 1];
b=[-6;-8;4;8];
A1=A;A1(:,1)=b;
A2=A;A2(:,1)=b;
A3=A;A3(:,1)=b;
A4=A;A4(:,1)=b;
D=det(A);
d(1)=det(A1); d(2)=det(A2); d(3)=det(A3); d(4)=det(A4);
x=d/D
P=A*x-b

спасибо,исправил в матрице, но все равно выдает туже ошибку
