A relatively simple question this time. I’m working on modifying some code to load two values as a vector type (double2) instead of as two doubles. Here’s a sample of the code I’m trying to use:
__global__ void mul_kernel(double2 g_z)
{
int threadID = blockIdx.x * blockDim.x + threadIdx.x;
double2 g_z_old = g_z[threadID];
g_z[threadID] = make_double2(g_z_old.x * g_z_old.x - g_z_old.y * g_z_old.y, g_z_old.x * g_z_old.y * 2.0);
}
And I get this error twice:
error: no operator “” matches these operands
operand types are: double2 [ int ]
So how am I supposed to index a vector type?
