BOOL GetReal( matrix & mReal )

Parameters

mReal: [output] matrix containing the Real part of this Complex matrix

Return

Returns TRUE on successful exit and FALSE on failure.

Examples

Remark

Get the Real part of a Complex matrix. Causes a runtime error if the underlying base type of the matrix is not Complex.
