WebDec 6, 2024 · % Any of the first four elements in SYS can be specified % as -1 indicating that they are dynamically sized. The % actual length for all other flags will be equal to the % length of the input, U. % SYS (5) = Reserved for root finding. Must be zero. % SYS (6) = Direct feedthrough flag (1=yes, 0=no). The s-function Web"Normalized" is used as a verb and means, "force a vector to have length 1." This is easily accomplished by dividing the vector by its magnitude. For example, the magnitude of 3i + 4j is 5, so the normalized version of this vector is (3/5)i + (4/5)j. The normalized version of a vector always has length 1 and is parallel to the original vector.
