Angular 4 animation - no animation / duration -


i try animate element in angular 4 in terms of height. regardless of whether use margin-bottom or height attributes changed, change done, without animation, meaning, height/margin-bottom value jumping 200px 0px immediately, without animation , without delay (if specified).

here animation code:

animations: [   trigger('ansichtstate', [     state('nursuche', style({       'margin-bottom': '200px'     })),     state('sucheundergebnisse', style({       'margin-bottom': '0px'     })),     transition('nursuche <=> sucheundergebnisse', animate('4000ms'))   ]) ]

the template code is:

<header [@ansichtstate]="currentansichtstate">&nbsp;</header>

currentansichtstate defined correctly , changed separate function.

also margin-bottom value changes 200px 0px done (although duration of 4000ms specified).

what doing wrong?

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
