CheckColumn — C interface function which checks if a parameter send to the C function is a column vector or not

CheckDimProp — C interface function which checks the comatibility between 2 arguments send to the C function

CheckDims — C interface function which checks if a parameter send to the C function has the required dimensions

CheckLength — C interface function which checks the length of a vector send as a parameter to the C function

CheckLhs — C macro which checks the number of output arguments present in the calling Scilab function.

CheckRhs — C macro which checks the number of input arguments present in the calling Scilab function.

CheckRow — C interface function which checks if a parameter send to the C function is a row vector or not

CheckSameDims — C interface function which checks if two parameters send to the C function have the same size

CheckSquare — C interface function which checks if a parameter send to the C function is a square matrix or not

CheckVector — C interface function which checks if a parameter send to the C function is a vector (column or row) or not

CreateListVarFrom — a C interface function which allows to create a new Scilab parameter in a [mt]list

CreateListVarFromPtr — a C interface function which allows to create a new Scilab parameter from a pointer in a [mt]list

CreateVar — a C gateway function which allows to create a new Scilab parameter

FindOpt — C gateway function find the position of an optional argument given its name

FirstOpt — C gateway function which returns the position of the first optional parameter

GetRhsVar — a C gateway function which allows to access an argument transmitted to a Scilab function

GetType — C gateway function which returns the type of a parameter in the Scilab memory

IsOpt — C gateway function which checks if a parameter is optional and returns the name of the parameter

Lhs — A C gateway function which provides the number of output arguments present in the calling Scilab function

LhsVar — a C gateway function which specifies which parameters created inside the C gateway will be returned as an output argument into Scilab.

NumOpt — C gateway function which returns the number of optional parameters sent to a C function

OverLoad — C gateway function which tells Scilab to look for another overloaded function

Rhs — A C gateway function which provides the number of input arguments present in the calling Scilab function
