I am trying to open two files(linoteste.ima and sysmattest.dat) they both contain one matrix. After successfully opening the files, when I print them, I only get matrices containing zeros and I don't know what I am doing wrong. This is not a CUDA related problem but a C one, its just that I am opening the files to do matrix multiplica开发者_JS百科tion with CUDA. My code is as follows (I have tried replacing fread with a while cicle to read one element at a time, but it does not work):
float*matlino=(float*)malloc(sizeof(float)*100*100);
float*matsys=(float*)malloc(sizeof(float)*10000*10000);
//Open linogram
FILE * flino, *fmat;
flino = fopen ("linoteste.ima","r"); //also tried with "rb" instead of "r"
if (flino!=NULL)
{
fread (matlino,sizeof(float),100*100,flino);
fclose (flino);
puts("Linograma aberto com sucesso");
}
else
puts("impossivel abrir linograma");
printMat(matlino,10,10);
//Open system matrix
fmat = fopen("sysmattest.dat","r");
if (fmat!=NULL)
{
fread (matsys,sizeof(float),10000*10000,fmat);
fclose (fmat);
puts("Matriz sistema aberta com sucesso");
}
else
puts("impossivel abrir matriz sistema");
Thanks in advance!
Have you tried fscanf()?
Something like:
if(flino!=NULL)
{
int i;
for(i = 0; i < 10000; i++) fscanf(flino, "%f", &malino[i]);
fclose(flino);
}
