Any chance we can have a look at the code ? I am guessing if you do geval(A); gysnc. before you do double(..) it would fail at gsync.
double(..) is a blocking operation so it waits until all previous gpu operations (related to A) are done. This may mean something else is broken and is being caught very late when doing double.

It would really be helpful if we can have a look at the code (or the smallest piece of code segment that will show this behavior) to figure this out.]]> no_email@example.com (pavanky) Programming & Development with Jacket for use with MATLAB® http://forums.accelereyes.com/forums/posting.php?mode=reply&f=7&t=4022 Wed, 16 May 2012 20:33:47 GMT http://forums.accelereyes.com/forums/viewtopic.php?f=7&t=4022&p=11921#p11921 Programming & Development with Jacket for use with MATLAB® :: Re: Fatal Matlab Error and ... http://forums.accelereyes.com/forums/viewtopic.php?f=7&t=4022&p=11923#p11923 Thanks,

two things.

- ArrayFire is zero based. so 1:15 would be 0:14.
- To get sequences, you qill have to use seq

seq can be used in two ways.

1) seq(start, end) will produce start, start+1, start+2, ..., end.
example: start(3, 5) == 3, 4, 5. seq(0, 4) == 0, 1, 2, 3, 4.
2) seq(elements) will produce 0, 1, 2, 3, 4, .... end - 1;
example seq(10) == 0, 1, 2, 3, 4, 5, ... 9;

so in your sampe code it can be one of the following
- dopmag(span, span, seq(0, zsamples - 1));
- dopmag(span, span, seq(zsamples));]]> no_email@example.com (pavanky) Programming & Development with ArrayFire for C, C++, Fortran, and Python http://forums.accelereyes.com/forums/posting.php?mode=reply&f=17&t=4014 Wed, 16 May 2012 20:10:28 GMT http://forums.accelereyes.com/forums/viewtopic.php?f=17&t=4014&p=11919#p11919 Programming & Development with ArrayFire for C, C++, Fortran, and Python :: Re: How doe ... http://forums.accelereyes.com/forums/viewtopic.php?f=17&t=4020&p=11920#p11920
This is a bug in interp. We are fixing this asap. When fixed, interp should work based on indices provided by hAi and not make any assumptions.]]> no_email@example.com (pavanky) Programming & Development with ArrayFire for C, C++, Fortran, and Python http://forums.accelereyes.com/forums/posting.php?mode=reply&f=17&t=4020 Wed, 16 May 2012 20:21:06 GMT http://forums.accelereyes.com/forums/viewtopic.php?f=17&t=4020&p=11920#p11920 Programming & Development with ArrayFire for C, C++, Fortran, and Python :: Re: max() ... http://forums.accelereyes.com/forums/viewtopic.php?f=17&t=3922&p=11922#p11922

The shortcut is failing because the compiler can not figure out the data type of {1, 2, 3, 4, 5};

If you specify the data type in the following manner, it should work.

Code: Select all: af::array myArray(1, 5, (float[]){1, 2, 3, 4, 5}); print(myArray);

myArray =
1.0000 2.0000 3.0000 4.0000 5.0000
