How to Find Vector Length in MATLAB Without Using Any MATLAB Functions?
-
How would I be able to find the length of a vector only using simple arithmetic and loops? For example, I can't use functions like find(), length(), fft(), etc.

Answer:
You should never need a loop in MATLAB to do vector operations. Edit: Use multiplication and transpose to compute the dot product. So for vector length, you could say: v_length = sqrt( v * v' ) The length of a vector is equal to the square-root of the sum of its elements.Unless you were referring to counting the number of entries in a vector?
