Boolean management
How to manage Scilab's boolean read and write process using call_scilab and api_scilab
Description
This help describes how boolean and matrix of booleans can be handle through the Call Scilab API and api Scilab.
There are several functions which can be used to read / write from the memory of Scilab. These functions are described in dedicated pages.
Note: Access to variables is done through api Scilab (named variable). |
Examples
/* * Write a matrix of boolean into Scilab * B=[F F T F; * F F F T ] * Note that it is done column by column */ 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"; SciErr sciErr; /* Write it into Scilab's memory */ sciErr = createNamedMatrixOfBoolean(pvApiCtx, variableNameB, rowB, colB, B); if(sciErr.iErr) { printError(&sciErr, 0); } /* * Prior to Scilab 5.2: * C2F(cwritebmat)(variableNameB, &rowB, &colB, B, strlen(variableNameB)); */ printf("Display from Scilab of B:\n"); SendScilabJob("disp(B);"); /* Display B */
/* Read the previously declared matrix of boolean B */ int rowB_ = 0, colB_ = 0, lp_ = 0; int i = 0, j = 0; int *matrixOfBooleanB = NULL; /* Int instead of double */ char variableToBeRetrievedB[] = "B"; SciErr sciErr; /* First, retrieve the size of the matrix */ sciErr = readNamedMatrixOfBoolean(pvApiCtx, variableToBeRetrievedB, &rowB_, &colB_, NULL); if(sciErr.iErr) { printError(&sciErr, 0); } /* * Prior to Scilab 5.2: * C2F(cmatbptr)(variableToBeRetrievedB, &rowB_, &colB_, &lp_, strlen(variableToBeRetrievedB)); */ /* Alloc the memory */ matrixOfBooleanB=(int*)malloc((rowB_*colB_)*sizeof(int)); /* Load the matrix */ sciErr = readNamedMatrixOfBoolean(pvApiCtx, variableToBeRetrievedB, &rowB_, &colB_, matrixOfBooleanB); if(sciErr.iErr) { printError(&sciErr, 0); } /* * Prior to Scilab 5.2: * C2F(creadbmat)(variableToBeRetrievedB,&rowB_,&colB_,matrixOfBooleanB,strlen(variableToBeRetrievedB) ); */ printf("\n"); printf("Display from B formatted (size: %d, %d):\n",rowB_, colB_); for(j = 0 ; j < rowB_ ; j++) { for(i = 0 ; i < colB_ ; i++) { /* Display the formatted matrix ... the way the user expects */ printf("%d ",matrixOfBooleanB[i * rowB_ + j]); } printf("\n"); /* New row of the matrix */ }
