I am trying to solve the error message 'incompatible ranks 0 and 1 in assignment' in a fortran 95 program. -

-

i writing program in fortran find velocity of parachuting person in relation time. keep getting error can't fix. new programming , appreciated.

the error is

v(i+1)=v(i)+[32-((c*v(i)*v(i))/m)]*(h) 1

error: incompatible ranks 0 , 1 in assignment @ (1)

and program is

program para integer :: real :: v(11) !velocity real :: q !initial velocity real :: h !time step real :: c !drag coefficient real :: m !mass  ! gravity equal 32 ft/s^2  write (*,*)'enter time step' read(*,*)h  write(*,*)'enter initial velocity' read(*,*)q  write(*,*)'enter drag coefficient' read(*,*)c  write(*,*)'enter mass' read(*,*)m  i=1,10 ! 1 10, 1 being interval. end  v(i+1)=v(i)+[32-((c*v(i)*v(i))/m)]*(h)  q=v(1)

end program

you cannot use [] normal parenthesis in expressions. array constructor, [ items ] means array items elements. end do should after line.

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).

getting video play cross platform using example video.js bit of fuss. in days when video should embedded use embed windows media player, work out of box on windows. since it's today old ie on windows doesn't support video tag experimented using windows media player fallback, , work well. what wonder here is, why haven't else solution? have missed something? code small, there's no flash files, cross domain issues or need of server working. works. so before develop further , add custom control , subtitles support wonder say. the code looks this: <video id="myvideo" style="width:640px; height: 360px;" autoplay data-wimpsource="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4"> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4" type="video/mp4" /> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.webm" type="video/webm" />
