i have filter data on bases of industry in angular 2.

i using query in pipe in angular 2 data not getting filtered.

filteredarray.filter(     item => item.value.filter(         inneritem => inneritem.industry.match(industry)))

make use of array.filter , array.some

let s = this.data.filter((d) => {       d.value = d.value.filter(d1 => {         if (d1.industry === "accounting") { // here put condition           return d1;         }       });       if (d.value.length > 0) {         return d;       }     }); 

var data = [      {      "key":"brochure",      "value":[{              "title":"accounting services",              "service":"accounting",              "location":"",              "industry":"accounting",              "reprint":"request",              "contact":"mike astrup",              "updated":"04/15/2017",              "owner":"eb",              "status":"approved",              "online":"true",              "type":"material",              "url":".common/service"          },          {              "title":"accounting services",              "service":"accounting",              "location":"",              "industry":"",              "reprint":"request",              "contact":"mike astrup 1",              "updated":"04/15/2017",              "owner":"eb",              "status":"approved",              "online":"true",              "type":"material",              "url":".common/service"          }]      },      {      "key":"handout",      "value":[{              "title":"accounting services",              "service":"accounting",              "location":"",              "industry":"",              "reprint":"request",              "contact":"mike astrup 2",              "updated":"04/15/2017",              "owner":"eb",              "status":"approved",              "online":"true",              "type":"material",              "url":".common/service"          },          {              "title":"accounting services",              "service":"accounting",              "location":"",              "industry":"",              "reprint":"request",              "contact":"mike astrup 3",              "updated":"04/15/2017",              "owner":"eb",              "status":"approved",              "online":"true",              "type":"material",              "url":".common/service"          }]      }  ];    var s = data.filter((d) => {  	 d.value = d.value.filter(d1 => {      if(d1.industry === "accounting") {     return d1;     }     });     if(d.value.length > 0){     return d;     }  });  console.log(s);

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);
