I'm trying to generate a 3D gaussian bell that looks like a ridge: in one dimension it would look like a normal gaussian bell, in the perpendicular dimension it would look like a rectangle. Mathematically you do this by having the variance (width of the bell) of one of the dimensions set to infinity (in Matlab you have the keyword "inf")... having a large number almost does the job but you still won't get a perfect rectangle.</DIV><DIV></DIV><DIV>Any suggestions will be very much appreciated.</DIV><DIV></DIV><DIV>Boris</DIV> Wed, 23 Feb 2011 10:05:02 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Infinity/m-p/795924#M2763 apolo74 2011-02-23T10:05:02Z https://community.intel.com/t5/Intel-Integrated-Performance/Infinity/m-p/795925#M2764 <P>Hi Boris, <BR /><BR />Not sure if it helps, In ippdef.h, thereis some definition about the value of IPP data type. <BR /><BR />#if defined( _WIN32 ) || defined ( _WIN64 )<BR /> #define IPP_MAX_64S ( 9223372036854775807i64 )<BR /> #define IPP_MIN_64S (-9223372036854775807i64 - 1 )<BR />#else<BR /> #define IPP_MAX_64S ( 9223372036854775807LL )<BR /> #define IPP_MIN_64S (-9223372036854775807LL - 1 )<BR />#endif</P><P>#define IPP_MINABS_32F ( 1.175494351e-38f )<BR />#define IPP_MAXABS_32F ( 3.402823466e+38f )<BR />#define IPP_EPS_32F ( 1.192092890e-07f )<BR />#define IPP_MINABS_64F ( 2.2250738585072014e-308 )<BR />#define IPP_MAXABS_64F ( 1.7976931348623158e+308 )<BR />#define IPP_EPS_64F ( 2.2204460492503131e-016 )<BR /><BR />Regards,<BR />Ying </P> Wed, 02 Mar 2011 04:59:16 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Infinity/m-p/795925#M2764 Ying_H_Intel 2011-03-02T04:59:16Z https://community.intel.com/t5/Intel-Integrated-Performance/Infinity/m-p/795926#M2765 Hi Ying,<DIV></DIV><DIV>sorry for my delay replying your tip... thanks, that's what I needed.</DIV><DIV></DIV><DIV>Boris</DIV> Mon, 14 Mar 2011 09:25:31 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Infinity/m-p/795926#M2765 apolo74 2011-03-14T09:25:31Z
