creadmat (obsolete)
Read a single double or a matrix of double from Scilab memory using call_scilab. Note that it is the default datatype in Scilab. Starting with Scilab 5.2, this function is obsolete. See API_Scilab: Double reading for remplacement.
int C2F(creadmat)(char *name, int *m, int *n, double *scimat, unsigned long name_len);
Arguments
- name
The name of the future Scilab variable
- m
Number of rows
- n
Number of columns
- scimat
The actual matrix of double (array of double). Note that it is going to be stored in Scilab columnwise.
- name_len
The length of the variable name(fortran compatibility)
- C2F
C2F is just a macro which provides to this function the ability to be called from fortran
Description
This help describes how to use the function creadmat.
Using this function will retrieve a variable called name from Scilab memory into a standard C double *.
Examples
/* Load the previously set variable B */ // See: modules/call_scilab/examples/basicExamples/readwritematrix.c int rowB_ = 0, colB_ = 0, lp_ = 0; double *matrixOfDoubleB = NULL; int i = 0, j = 0; char variableToBeRetrievedB[] = "B"; /* First, retrieve the size of the matrix */ C2F(cmatptr)(variableToBeRetrievedB, &rowB_, &colB_, &lp_, strlen(variableToBeRetrievedB)); /* Alloc the memory */ matrixOfDoubleB = (double*)malloc((rowB_*colB_)*sizeof(double)); /* Load the matrix */ C2F(creadmat)(variableToBeRetrievedB,&rowB_,&colB_,matrixOfDoubleB,strlen(variableToBeRetrievedB) ); printf("\n"); printf("Display from B formated (size: %d, %d):\n",rowB_, colB_); for(j = 0 ; j < rowB_ ; j++) { for(i = 0 ; i < colB_ ; i++) { /* Display the formated matrix ... the way the user * expect */ printf("%5.2f ",matrixOfDoubleB[i * rowB_ + j]); } printf("\n"); /* New row of the matrix */ }
