From: Harley Wei on 6 May 2008 04:34 I want to solve some questions in Matlab7.0 like solve('angle(1-1/(i*x+0.5))=pi/2','x') but ???Error using ==>solve 'angle(1-1/(i*x+0.5))=pi/2' is not a valid expression or equation. why angle() can not work in solve(), but abs() does. How can I do if I want to solve this question, thanks. |
