API common functions
This page lists all the functions to get information about Scilab native objects.
scilabVar
scilab_getVar(const wchar_t* name)Return variable called name, NULL if variable does not exist.
int scilab_isDouble (env,
var)
int
env,
var)
int
env,

int

int
env,

int
env,

int
env,
var)
Return 1 if variable var has the right type.
int scilab_getDim(
scilabEnv
env,
scilabVar
var)
Return the number of dimension of var. Note that scalar variables are 2d matrix of dimension (1, 1)
int scilab_getDim2d(
scilabEnv
env,
scilabVar
var, int* row, int* col)
Return dimensions of a 2d variable var in row and col.
int scilab_getDimArray(
scilabEnv
env,
scilabVar
var, const int** dims)
Return pointer on array of dimensions of a variable var in dims.
int scilab_getSize(
scilabEnv
env,
scilabVar
var)
Return size of variable var.
For matrix type is the result of product of dimension and for others like list is the item count.
int scilab_isMatrix2d(
scilabEnv
env,
scilabVar
var)
Return 1 for matrix with 2 dimensions and scalar.
int scilab_isSquare(
scilabEnv
env,
scilabVar
var)
Return 1 for matrix with 2 dimensions and dimensions have the same size.
int scilab_isVector (env,
var)
int
env,
var, int n)
int
env,
var)
int
env,
var)
Use to check if variable var is a vector. n is the dimension to check, scilab_isRowVector is equivalente to scilab_isNVector(env, var, 1)
int scilab_isHypermat(
scilabEnv
env,
scilabVar
var)
Return 1 for matrix with dimensions count is up to 2.
int scilab_overload(
scilabEnv
env,
scilabVar
var, int nin,
scilabVar
*in, int nout,
scilabVar
*out)
Call an overload function following type of var.
nin, in, nout, out must be used like in gateway prototype.
int scilab_call(
scilabEnv
env, const wchar_t* name, int nin,
scilabVar
*in, int nout,
scilabVar
*out)
Call function name.
nin, in, nout, out must be used like in gateway prototype.
Examples
#include "api_scilab.h" #include "Scierror.h" #include "localization.h" const char fname[] = "overload_test"; int sci_overload_test(scilabEnv env, int nin, scilabVar* in, int nopt, scilabOpt opt, int nout, scilabVar* out) { if (nin < 1 || nin > 2) { Scierror(999, _("%s: Wrong number of input arguments: %d to %d expected.\n"), fname, 1, 2); return STATUS_ERROR; } //call overload function if (nin == 1) { return scilab_overload(env, in[0], nin, in, nout, out); } else // call function in[0] with in[1] as argument { wchar_t* name = NULL; if (scilab_isString(env, in[0]) == 0 || scilab_isVector(env, in[0]) == 0) { Scierror(999, _("%s: Wrong type for input argument #%d: string expected.\n"), fname, 1); return STATUS_ERROR; } scilab_getString(env, in[0], &name); return scilab_call(env, name, nin - 1, in + 1, nout, out); } return STATUS_OK; }
