Matlab - modify class attributes -


i'm trying simulate car's position matlab. far have created class representing car public attributes position (obj.position), speed (obj.vist) , delta (obj.delat). delta represents time steps. when let car drive want change it's position adding actual speed. unfortunately isn't working...

the code

fprintf(' \n position: %4.0f',  obj.position ); obj.position = obj.position + obj.vist*obj.delta; fprintf(' \n position: %4.0f',  obj.position );

creates following output:

position: 1000 position:

what doing wrong? has handle or value class? i'm pretty sure question stupid im starting work matlab i'm needing here...

thanks in advance.

the class definition:

classdef mycar < handle     %untitled summary of class goes here     %   detailed explanation goes here  properties     id;     typ;     startzeit;     vstart;     posstart;      position;     vist;     vsoll;     vmax;     laenge;     aktiv = false;     vmaxstrecke;      poi;     vpoi;     poiaktiv = false;      bremswegzumpoi;     bremsverzoegerung = 0.8;      ageg = [];     vgeg = [];     delta;      zeitlinie = [];     vistlinie = [];     poslinie= [];     vsolllinie = []; end  methods     function drive(obj, time)             fprintf(' \n in fahre: %4.0f',  obj.position );             obj.position = obj.position + obj.vist*obj.delta;             fprintf(' \n in fahre: %4.0f',  obj.position );              obj.zeitlinie = [obj.zeitlinie, time];             obj.vistlinie = [obj.vistlinie, obj.vist];     end end end

the method drive called script managing several cars.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
