Hi, I seem to get some strange result with CUFFT 3D. If I run it on a 128 x 128 x 128 volume and compare with fftn in Matlab it gives the same result, also for 128 x 256 x 128, but not for 256 x 128 x 128 or 128 x 128 x 256.

I guess it can have something to do with that Matlab saves data column by column instead of row by row, but I try to compensate for this when I read the data from Matlab

I read a real-valued volume from Matlab like this

```
void pack_r2c(Complex *output_float,
double *input_re, int DATA_W, int DATA_H, int DATA_D)
{
int i = 0;
for (int z = 0; z < DATA_D; z++)
{
for (int x = 0; x < DATA_W; x++)
{
for (int y = 0; y < DATA_H; y++)
{
output_float[x + y * DATA_W + z * DATA_W * DATA_H].x = (float)input_re[i];
output_float[x + y * DATA_W + z * DATA_W * DATA_H].y = 0.0f;
i++;
}
}
}
}
```

Is there any difference between using

cufftComplex

and

typedef float2 Complex ?
