Negative inputs to this block return a value of zero.
The implementation of this block does not call the corresponding Texas Instruments library function during code generation. The TI function uses a global Q setting and the MathWorks® code used by this block dynamically adjusts the Q format based on the block input. See Using the IQmath Library for more information.
Whether to calculate the square root or inverse square root
Square root (_sqrt)— Compute the square root.
Inverse square root (_isqrt)— Compute the inverse square root.
