Hi,
I'm new in X10 and I see that arrays in X10 are really "awesome" ... but
will take me some time to fully understand how to work with them. I
understand that arrays are indexed by points, etc., and are "different"
from C or java-like arrays. For now lets talk about the simple, not
distributed arrays.
Now, before I go in detailed reading of the specifications, I would like
to see fairly straightforward example that would help me understand what
are the best ways to handle multi-dimensional arrays.
Let's start with a simple case of dynamically allocated matrix
representation in array. In C one might do something like that:
int rows, columns;
double **matrix;
// typically would be set dynamically from some kind of input,
// let's just make it simple for this example
rows = 2;
columns = 3;
matrix = malloc(rows * sizeof(double*));
for (i = 0; i < rows; i++) {
matrix[i] = malloc(columns * sizeof(double*));
}
// typically would be set dynamically from some kind of input,
// let's just make it simple for this example
m1[0][0] = 1.01;
m1[0][1] = 2.19;
m1[0][2] = 3.28;
m1[1][0] = 2.12;
m1[1][1] = 4.61;
m1[1][2] = 3.44;
---
No, how would one do this in X10? As I understand there is probably more
that one way to do it? There are probably "performance-wise" and
"c/java-like" ways to do it?
Many thanks for help!
Kind regards, Marko Kobal
