i have 2 html date pickers having trouble with. trying set value , apply minimum , maximum criteria knockout. after research found the proper date format proper format value, min, , maximum. trouble is, min , max not seem work. here html date picker: <input type="date" data-bind="value: mindate, min: mindaterange, max: maxdaterange" /> the format of dates yyyy-mm-dd in accordance link sent. if manually apply min , max attributes date format works fine. have idea doing wrong? you can't use min , max because there no such bindinghandlers. can use attr bindinghandler: <input type="date" data-bind="value: mindate, attr: { min: mindaterange, max: maxdaterange }" />

how can use matlab solve following ordinary differential equations? x''/y = y''/x = -( x''y + 2x'y' + xy'') with 2 known points, such t=0: x(0)= x0, y(0) = y0; t=1: x(1) = x1, y(1) = y1 ? doesn't need complete formula if difficult. numerical solution ok, means, given specific t, can value of x(t) , y(t). if matlab hard this, mathematica ok. not familiar mathematica, prefer matlab if possible. looking forward help, thanks! i asked same question on stackexchange, haven't answer yet. https://math.stackexchange.com/questions/812985/matlab-or-mathematica-solve-ordinary-differential-equations hope can problem solved here! what have tried is: ---------matlab syms t >> [x, y] = dsolve('(d2x)/y = -(y*d2x + 2dx*dy + x*d2y)', '(d2y)/x = -(y*d2x + 2dx*dy + x*d2y)','t') error using sym>convertexpression (line 2246) conversion 'sym' returned mupad error: error: unexpected ...

well on last day of school trying finish program , can't life of me past null reference exception. code supposed average [count] numbers entered user using stack of integers. throwing null reference exception because attempted count of stack empty, added line push 0 on it. program stops @ line same error (nullreferenceexception). if change stack accept strings works fine, need accept integers. can :) module module1 sub main() dim count integer = 16 dim stack new stack(of integer) stack.push(0) console.writeline("please enter " & count & " numbers") while stack.count - 1 = count stack.push(console.readline) if not isnumeric(stack.peek) console.writeline(stack.pop & " not number please try again.") end if loop end sub end module you're declaring variable named stack , not creating stack object. instead (with new k...
