I’ve been having an issue with a certain function call in the dphaseWeighted = af::convolve(dphaseWeighted, m_slowTimeFilter); which seem to produce nothing but nan’s. The back ground is we have recently switched from using AF OpenCL to AF Cuda and the problem that we are seeing happens in the function. dphaseWeighted = af::convolve(dphaseWeighted, m_slowTimeFilter); This seems ..

I have an ArrayFire array of dtype=f64 that I need to cast to dtype=f32. I’m not sure how to do this other than converting to a host array and iterating through doing a static_cast. I’m sure there is a better way. I found af_cast but it seems to only be a part of the C ..
If I use A(i, span) = A(i, span) + 1; within gfor it works. But what if I want to use a limited range instead of a full span of a dimension: gfor(seq i, A.elements()) { A(i, span) = A(i, span) + 1; // this works A(i, i+3) = A(i, i+3) + 1; // compile ..
How to search for a sequence within ArrayFire. Is it possible to locate occurrence indices? Is it possible to match all occurrences at once? Is it possible to search for multiple sequences (multi-pattern) at once? Is it possible to set a value (ex: -1) as ? wildcard? if no, what’s the trick to do the ..
