Hi,
I tried to use gsl_matrix_fread() to read in a matrix but failed as soon as
I did not use the example program given in the manual.
My working enviroment is: PC, Windows 2000 Professional, Visual C++ 6.0, in
addition to the default settings of the program I activated the 'Disabled
Language Extensions' and switched to 'Multithresded DLL' (I do need this
enviroment for the rest of my program).
I do get the following error message:
"gsl: C:\Windows\Desktop\gsl-1.3\block\fwrite_source.c:64: ERROR: fread
failed
Default GSL error handler invoked.
abnormal program termination"
the test programm looks as follows:
#include <stdio.h>
#include <gsl/gsl_matrix.h>
void main()
{
gsl_matrix *mat = gsl_matrix_alloc(10,10);
int i,j;
FILE *f = fopen("readin.bin","w");
for (i=0;i<10;i++)
{
for (j=0;j<10;j++)
{
double tmp = (5*i+7.8*j)/10.0;
gsl_matrix_set(mat,i,j,tmp);
}
}
gsl_matrix_fwrite(f,mat);
fclose(f);
{
f = fopen("readin.bin","r");
gsl_matrix_fread(f,mat);
fclose(f);
}
gsl_matrix_fprintf(stderr,mat,"%.4f");
printf("\n");
gsl_matrix_free(mat);
return;
}
Thanks a lot.
Annett
