cequal

cequal (z1, z2)

The cequal function determines the equality of two complex numbers z1 and z2. It returns 1 if they are equal, or 0 if not.

This is in contrast to the == operator, which compares only the real components of z1 and z2, ignoring the imaginary components.

Examples

Function TestComplexEqualities()
	Variable/C z1= cmplx(1,2), z2= cmplx(1,-2)

	// This test compares only the real parts of z1 and z2:
	if( z1 == z2 )
		Print "== match"
	else
		Print "no == match"
	endif

	// This test compares both real and imaginary parts of z1 and z2:
	if( cequal(z1,z2) )
		Print "cequal match"
	else
		Print "no cequal match"
	endif
End
