MAGNITUDE
Magnitude(X) returns the magnitude (also called modulus or absolute value) of a complex variable X. In complex mode, the ABS function also returns the magnitude. Representing X as X_r + i*X_i, this function returns sqrt(X_r^2+X_i^2).
Example: Y=Magnitude(X)
The above example will set the real part of Y (Y_r) to the magnitude of X and the imaginary part of Y to zero.
Note that the Magnitude function is used to extract the magnitude of a complex number variable or expression. It cannot be used for assigning the magnitude of a complex number. For example, the equation Magnitude(X)=4 will produce an error.
