javascript - Slow down setAttribute() -

-

is possible slow down setattribute()? example, have following code:

function hide(i) {     var previewdiv = document.getelementbyid('preview');     var fulldiv = document.getelementbyid('full');     previewdiv.setattribute('style', 'display:normal;');     fulldiv.setattribute('style', 'display:none;'); }

now want make display:none go display:normal delay "fades" open instead of bluntly open. or there way achieve this?

it can done in multitude of ways. use jquery's fadein method $('.element').fadein(); or using css , javascript. found example http://www.chrisbuttery.com/articles/fade-in-fade-out-with-javascript/ chris buttery.

i comes down taste. although 1 argue second option should more optimal on systems.

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,
