I have a two dimensional array that I've allocated dynamically using new.
The problem is I want to allocate the memory as one connected block instead of in separated pieces to increase processing speed.
Does anyone know if it's possible to do this with new, or do I have to use malloc?
Here's my code:
A = new double*[m];
for (int i=0;i<m;i++)
{
A[i]= new double[n];
}
This code causes a segmentation fault
phi = new double**[xlength];
phi[0] = new double*[xlength*ylength];
phi[0][0] = new double[xlength*ylength*tlength];
for (int i=0;i<xlength;i++)
{
for (int j=0;j<ylength;j++)
{
phi[i][j] = phi[0][0] + (ylength*i+j)*tlength;
}
phi[i] = phi[0] + ylength*i;
}
