defining different cases for function im matlab (symfun) -


i want create function (symfun), , want divide cases, i.e if t> then answer , if t<0 answer b. thing is, matlab wont allow me put if statements after sym function.

>> l = symfun(0, [m]); >> l(m) = if m>0 3

also tried create function:

function [x1] = xt_otot_q3(t)

and tried connect between 2 functions:

>> l(m) = xt_otot_q3(m) conversion logical sym not possible.

is there way break symfun cases?

not sure understand want. code 'combines' functions symfun , xt+otot_q3 defined below:

function test;    m=randn(4);               % n(0,1) random numbers   l=xtotot_q3(symfun(0,m))  % combine xt_otot_q3 , symfun    l=symfun(0,xtotot_q3(m))  % combine symfun , xt_otot_q3 return  function lval=symfun(thr,rval);    lval=ones(size(rval));    % output, size of input, = 1    lval(rval<thr)=-1;        % output = -1 if input < thr  return  function lval=xtotot_q3(rval);    lval=3*rval+1;            % function, in case 3 * input + 1  return

you can save whole bit test.m , call test matlab prompt. maybe if start can modify fit needs.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
