creadcmat (obsolete)
Read a single complex or a matrix of complex from Scilab memory using call_scilab. Starting with Scilab 5.2, this function is obsolete. See API_Scilab: Complex double reading for remplacement.
int C2F(creadcmat)(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 complex (array of double). Note that it is going to be stored in Scilab columnwise and the second half of the array is used for complex values.
- 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 creadcmat.
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/readwritecomplexmatrix.c int rowB_ = 0, colB_ = 0, lp_ = 0; int i = 0,j = 0; double *matrixOfComplexB = NULL; char variableToBeRetrievedB[] = "B"; /* First, retrieve the size of the matrix */ C2F(cmatcptr)(variableToBeRetrievedB, &rowB_, &colB_, &lp_, strlen(variableToBeRetrievedB)); /* Alloc the memory */ matrixOfComplexB = (double*)malloc((rowB_*colB_*2)*sizeof(double)); /* Load the matrix */ C2F(creadcmat)(variableToBeRetrievedB,&rowB_,&colB_,matrixOfComplexB,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 + %5.2f.i ",matrixOfComplexB[i * rowB_ + j],matrixOfComplexB[(rowB_*colB_)+(i * rowB_ + j)]); } printf("\n"); /* New row of the matrix */ }
