https://community.intel.com/t5/Intel-Integrated-Performance/ippsMul-32f32fc-changes-input-array/m-p/1227835#M27473 <P>Hi all,</P> <P>I found something unexpected using the&nbsp;<FONT style="background-color: #ffffff;">ippsMul_32f32fc</FONT> function. Its description says that it multiplies the elements of two source arrays and stores the result in a destination array. Checking my two source arrays after the operation, I see that the second source array values have been changed. Even though this is perfectly possible, given the fact that we use a const pointer, but not necessarily const values, I would still expect that this function would not change the source arrays, or at least there should be a warning that it does.</P> <P>Is this intended and should I just not try to reuse my source array, or is it actually not supposed to happen. Thanks for your help!</P> Thu, 12 Nov 2020 15:15:42 GMT YNNL 2020-11-12T15:15:42Z https://community.intel.com/t5/Intel-Integrated-Performance/ippsMul-32f32fc-changes-input-array/m-p/1227835#M27473 <P>Hi all,</P> <P>I found something unexpected using the&nbsp;<FONT style="background-color: #ffffff;">ippsMul_32f32fc</FONT> function.
