Forgive me if this is redundant or super basic. I'm coming to Python/Numpy from R and having a hard time flipping things around in my head.
I have a n dimensional array which I want to sort using another n dimensional array of index values. I know I could wrap this in a loop but it seems like there…

Hello,
I am playing around with multidimensional array of unequal second dimension size.
Lets assume that I need the following data structure:

[&ptr1]-[0][1][2]
[&ptr2]-[0][1][2][3][4]
int main()
{
int *a[3];
int *b;
int i;
a[0] = (int *)malloc(10…

I have a php form that has a known number of columns (ex. top diameter, bottom diameter, fabric, colour, quantity), but has an unknown number of rows, as users can add rows as they need.
