Fortran to matlab 'undefined function error' -


i want covert fortran matlab.

-fortran code

   20 i=1,3    20 j=1,4 20 wormx(i,j)=0.0     24 inode=1,8    ipoin=iabs(lnods(ielem,inode0)    24 k=1,3    gtop=coord(ipoin,k)    gbot=coord(ipoin,k+4)    gosh=((1.0+zeta)*gtop+(1.0-zeta)*gbot)/2.0    22 j=1:3 22 wormx(k,j)=wormx(k,j)+gosh*shape(j,inode) 24 wormx(k,4)=wormx(k,4)=wormx(k,4)+shape(1,inode)*gtop-bbot)/2.0     call matm(2,5,0,1)

. . . -matlab code

function func   global lnods coordi shape nelem dzetta  i=1:3     j=1:4         wormx=zeros(i,j);     end  end   shape=zeros(3,9);  inode=1:8      ielem=1:nelem          ipoin=abs(lnods(ielem,inode));          k=1:3              gtop=coordi(ipoin,k);              gbot=coordi(ipoin,k+4);              gosh=((1.0+0.91)*gtop+(1.0-0.91)*gbot)/2.0;              j=1:3              wormx(k,j)=wormx(k,j)+gosh*shape(j,inode);              end              wormx(k,4)=wormx(k,4)+shape(1,inode)*(gtop-gbot)/2.0;           end      end  end   matm(2, 5, 0, 1)

. .

i got error message in matlab code, 

"undefined function or method 'matm' input arguments of type 'double'."

what's problem in code?

your fortran code calls procedure matm. if fortran code not error, presumably procedure defined somewhere.

have translated procedure matm matlab yet? if not, issue - when matlab gets point matm(2, 5, 0, 1) fails, function matm not defined.

if have translated matm matlab, issue matlab cannot find function matm. perhaps need add location of matm matlab path.

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...
