i have matlab code i've been working with. there 3 sections, a, b, , c. , c can change, b stays same regardless. what did separate a, b, , c separate .m files (not functions, scripts). creates set of variables, b contains logic, , c contains plotting results. i'll call d file i've done linearly copy/paste entire contents of a, b, , c right after each other. if run a, b, c, iteration within b goes slowly, 15 seconds per iteration. if run d (just b c pasted in) goes fast, 2 seconds per iteration. given matlab running exact same code in exact same order, why 2 have such drastically different execution times? i believe have memory issues. matlab functions input variables pointers, if change data, becomes copy. if a,b,c have large input , output, , each 1 of them modifies small part of data, lot of memory allocations. for example: function main() x = imread('peppers.png'); i=1:size(x,1) j=1:size(x,2) x = changepixel(x,i,j); en...

i don't quite understand how pointers work c arrays. here's code got: int arrayone[] = {1, 2, 3}; int arraytwo[] = {4, 5, 6, 7}; int **arraythree = (int **)malloc(2 * sizeof(int)); arraythree[0] = arrayone; arraythree[1] = arraytwo; (int = 0; < 2; i++) { int *array = arraythree[i]; int length = sizeof(array) / sizeof(int); (int j = 0; j < length; j++) printf("arraythree[%d][%d] = %d\n", i, j, array[j]); } i have expected output following: arraythree[0][0] = 1 arraythree[0][1] = 2 arraythree[0][2] = 3 arraythree[1][0] = 4 arraythree[1][1] = 5 arraythree[1][2] = 6 arraythree[1][3] = 7 what prints out is: arraythree[0][0] = 1 arraythree[0][1] = 2 arraythree[1][0] = 4 arraythree[1][1] = 5 why?! sizeof(array) size of pointer, happens twice size of int on platform. there's no way length of array in c. have remember yourself.

i'm trying convert "hello" 48 65 6c 6c 6f in hexadecimal efficiently possible using command line. i've tried looking @ printf , google, can't anywhere. any appreciated. many in advance, echo -n "hello" | od -a n -t x1 explanation: the echo program provide string next command. the -n flag tells echo not generate new line @ end of "hello". the od program "octal dump" program. (we provide flag tell dump in hexadecimal instead of octal.) the -a n flag short --address-radix=n , n being short "none". without part, command output ugly numerical address prefix on left side. useful large dumps, short string unnecessary. the -t x1 flag short --format=x1 , x being short "hexidecimal" , 1 meaning 1 byte.

in iphone app need user able enter decimal amount in textfield , need convert float. i use following code: cgfloat amount = [amounttextfield.text floatvalue]; it works fine when user , use point decimal values, european users use comma instead doesn't value. should replace , . before using floatvalue or there better way? a better way use nsdecimalnumber, floats ugly anyway. because 2.2 should 2.2 , not 2.2000000477 nsdecimalnumber *amount = [nsdecimalnumber decimalnumberwithstring:amounttextfield.text locale:[nslocale currentlocale]]; if don't want use nsdecimalnumber have nsnumberformatter , nsnumber. convert cgfloat (which name float) too. when comes localization want use built-in functionality. when use string editing doing wrong.
