javascript - Angular [ngClass] vs [class -


what difference in angular between following snippets:

<div [class.extra-sparkle]="isdelightful"> <div [ngclass]="{'extra-sparkle': isdelightful}">

this special angular binding syntax

<div [class.extra-sparkle]="isdelightful">

this part of angular compiler , can't build custom binding variant following binding style. supported [class.xxx]="...", [style.xxx]="...", , [attr.xxx]="..."

ngclass normal angular directive can build 

<div [ngclass]="{'extra-sparkle': isdelightful}">

ngclass more powerful. allows bind string of classes, array of strings, or object in example.

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);
