Hello!

Is there any way to access vector elements in a loop with a variable?

I'm looking for something like this:

int16 temp;
for (i = 0; i < 16; i++){
temp.s(i)= i;
}

or do i have to do it like this

temp.s0 = 0;
temp.s1 = 1;
etc.

?

Dynamically indexing into a vector is not allowed as a vector is not an array.

Thanks for the quick reply.

How about an arithmetic workaround then? How does shifting on vector datatypes work? Does the carry bit transfer to the neighbouring element?

Please see the OpenCL spec on shift operations on Vectors. It states that they are done per component.

Indeed. Thank you
