Description
The function ippmCrossProduct is declared in the ippm.h header file. The function composes a vector product of two source vectors. The first element in the destination vector is obtained by subtracting the product of the third element in the first source vector and the second element in the second source vector from the product of the second element in the first source vector and the third element in the second source vector.
The following relations are used in computing the first destination element and the other two elements: 
The result is stored in the destination vector.
Return Values
ippStsOk |
Returns no error. |
ippStsNullPtrErr |
Returns an error when at least one input pointer is NULL. |
ippStsSizeErr |
Returns an error when the input size parameter is equal to 0. |
ippStsStrideMatrixErr |
Returns an error when the stride value is not positive or not divisible by size of data type. |
ippStsRoiShiftMatrixErr |
Returns an error when the roiShift value is negative or not divisible by size of data type. |
ippStsCountMatrixErr |
Returns an error when the count value is less or equal to zero. |
Note
The function ippmCrossProduct is defined only for three-dimensional vectors and fails with all other argument types.
