  • MATRIX_OF_STRING_DATATYPE "S"

  • MATRIX_OF_DOUBLE_DATATYPE "d"

  • MATRIX_OF_RATIONAL_DATATYPE "r"

  • MATRIX_OF_VARIABLE_SIZE_INTEGER_DATATYPE "I"

  • EXTERNAL_DATATYPE "f"

  • MATRIX_OF_POLYNOMIAL_DATATYPE "x"

m_rows

the number of lines of the matrix to be created (input argument)

n_cols

the number of columns of the matrix to be created (input argument)

l_stack_pos

the position in the Scilab memory of the created parameter (output argument)

Description

A C gateway function which allows to create a new Scilab parameter

WARNING: This API is deprecated from Scilab 5.2.0 and is going to be removed with Scilab 6.0. Please use API Scilab (the new Scilab API).

Examples

#include <stack-c.h>

int sci_myones(char * fname)
{
  int m_row, n_col, l_pos;
  
  m_row = 1; n_col = 1; // We create a scalar
  CreateVar(1, MATRIX_OF_INTEGER_DATATYPE, &m_row, &n_col, &l_pos);

  *istk(l_pos) = 1;

  LhsVar(1) = 1;

  return 0;
}
