cwritebmat (obsolete)

Write a single boolean or a matrix of boolean into Scilab memory using call_scilab. Starting with Scilab 5.2, this function is obsolete. See API_Scilab: Boolean writing for remplacement.

int C2F(cwritebmat)(char *name, int *m, int *n, int *mat, unsigned long name_len);



The name of the future Scilab variable


Number of rows


Number of columns


The actual matrix of boolean (array of int). Note that it is going to be stored in Scilab columnwise.


The length of the variable name (fortran compatibility)


C2F is just a macro which provides to this function the ability to be called from fortran


This help describes how to use the function cwritebmat.

Using this function will basically do the same as A=[ T F F T ]; but straight into Scilab memory with call_scilab.


// This example shows how to write a Scilab matrix of boolean in Scilab engine
// It is the equivalent to 
// B=[F F T F;
//    F F F T ] in Scilab interpretor
// See: modules/call_scilab/examples/basicExamples/readwriteboolean.c

// StartScilab
int B[]={0,0,0,0,1,0,0,1};   /* Declare the matrix */
int rowB=2, colB=4; /* Size of the matrix */
char variableNameB[] = "B";
C2F(cwritebmat)(variableNameB, &rowB, &colB, B, strlen(variableNameB)); /* Write it into Scilab's memory */
printf("Display from Scilab of B:\n");
SendScilabJob("disp(B);"); /* Display B */
