matlab - Custom Curve-Fitting equation doesn' t works -

i trying fit custom equation cumsu=a+b*(1586-x).^m estimate parameters a,b,m. data: cumsu=[...];%the reason don't give vector cumsu large number of values included. x=[1:1586]; i thankful if can helps me. thank in advance! you can create custom fitting models via fit function . fitobject = fit(x,y,fittype,fitoptions) in case should replace fittype fitting equation: customfit=fit(x,cumsu,'a+b*(1568-x)^m') with random numbers output was: general model: f(x) = a+b*(1568-x)^m coefficients (with 95% confidence bounds): = -2.011 (-2.959e+06, 2.959e+06) b = 1.479 (-2.424e+06, 2.424e+06) m = 0.1049 (-9.702e+04, 9.702e+04)

as part of security hardening, trying disable local_infile , prevent accessing local files of operating system. per documentation can disable either setting variable local-infile=0 in my.cnf or start mysqld service option --local-infile=0 . of option able load local files. i tried first adding in /etc/my.cnf [mysqld] local-infile=0 after confirmed changes got reflected. mysql> show global variables 'local_infile'; +---------------+-------+ | variable_name | value | +---------------+-------+ | local_infile | off | +---------------+-------+ 1 row in set (0.00 sec) then mysql client loaded local file using load_file mysql> select load_file("/etc/passwd"); the above command shows content of /etc/passwd file, though local_infile disabled.can tell going wrong here? i repeated same steps passing mysqld --local-infile=0 no change. have tried starting mysql client --local-infile=0 option no difference. use query in mysql database

visual studio - 32-bit .obj in 64-bit project -

i have 32-bit object file o.obj , want use in project uses 64-bit library l.lib . to make .lib happy, visual studio configuration needs set x64. however, linker throws error of error lnk1112: module machine type 'x86' conflicts target machine type 'x64' . i went through visual studio's linker options, nothing jumped out. there way resolve error? i under impression 32-bit code compatible 64-bit systems, modulo libraries. x86 executables (that is, object code compiled 32-bit x86 processors) can executed on x64 machines running 64-bit operating systems, through special compatibility mode supported jointly processor , operating system. feasible because x86 instruction set subset of x64 instruction set. however, many elements of abi differ between x86 , x64 code, notably calling conventions , pointer size. calling convention needs match between calling code , called code, or things screw up. thus, there no straightforward way call 64-bit code 32-b

c - What is Partial Linking in GNU Linker? -

the best explanation able find official document: -r --relocateable generate relocatable output--i.e., generate output file can in turn serve input ld. called partial linking. side effect, in environments support standard unix magic numbers, option sets output file's magic number omagic. if option not specified, absolute file produced. when linking c++ programs, option not resolve references constructors; that, use -ur. option same thing `-i'. i interested in knowing happens symbols present in inputs linker. take specific case when have static library libstatic.a contains single object file component.o . now, want create static library libfinal.a work interface libstatic.a . use command create it: ld -r -o libfinal.a wrapper.o -l. -lstatic where wrapper.o provides exclusive apis call functions defined in libstatic.a will libfinal.a combined archive having wrapper.o , component.o or references can-be-resolved between wrapper.o , component.

javascript - SuccessCallback firing immediately in Xrm.Page.data.save -

i writing javascript code change form of entity in dynamics crm based on value of field on each form. to change form, user has change value of field. during onchange event, js comes in, triggers saving, has wait result , change form. (if save , change @ same time, there still window shown asking user confirm leaving unsaved changes) now there should way that: xrm.page.data.save(saveoptions).then(successcallback, errorcallback) as described on msdn : saves record asynchronously option set callback functions executed after save operation completed. i using such: var campaigntype = xrm.page.getattribute('typecode').getvalue(); if (xxx.forms.hasownproperty(campaigntype)) { xrm.page.data.save().then(function () { xxx.redirecttoform(xxx.forms[campaigntype]); }, null); but form change still triggered during save. what doing wrong? i faced similar problem while trying update process bar. xrm.page.data.save().then (function () {
