MATLAB execute function for multiple variables in loop -


to process data in matlab have execute function, let's call function(). since there data processed, large array time or voltage (but many more) execute 1 one this:

timenew = function(time); voltagenew = function(voltage); ... etc

so done around 10 times. moreover, have such thing multiple times, resulting in around 30 lines of code same thing different variable.

is there way optimize this? using recent version of matlab (2015b) , have toolboxes installed.

a possible solution store input array struct, them use struct input of function.

in function can identify number , content of each field using fieldnames , getfiled built-in function.

the function return structure output names can made same ones of input struct.

in example below, 3 arrays generated , function siply compute square.

var_1=1:10; var_2=11:20; var_3=21:30;  str_in=struct('var_1',var_1,'var_2',var_2,'var_3',var_3)  str_out=my_function(str_in)

the function

function [str_out]=my_function(str_in) f_names=fieldnames(str_in) n_fields=length(f_names);  i=1:n_fields    x=getfield(str_in,f_names{i})    str_out.(f_names{i})=x.^2; end

hope helps.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
