Hi there, I am trying to extract the absolute value of the column vectors inside an array, but it keep giving me the message: Array indices must be positive integers or logical values., for the fol. Not the answer you're looking for? which is also the norm, of the complex variable after fft. The absolute value of -9 is 9 written | -9 | = 9. How do I erase an element from std::vector<> by index? Choose a web site to get translated content where available and see local events and syms x simplify (abs (x)^2) ans = abs (x)^2. MathWorks is the leading developer of mathematical computing software for engineers and scientists. The Absolute value is symbolized by vertical bars, as in |x|, |z|, or |v|, and . The absolute value in maths is defined as the value which describes the distance of a number on the number line from 0 without taking into consideration which direction from zero the number lies.
