Gridpp in C plus plus

Example code

include <gridpp.h>

int main(void) {

    // Create some fake data
    coarse_lats = gridpp::init_vec2(6, 5);
    coarse_lons = gridpp::init_vec2(6, 5);
    coarse_temperature = gridpp::init_vec2(6, 5);
    for(int y = 0; y < 6; y++) {
        for(int x = 0; x < 5; x++) {
            coarse_lats[y][x] = y;
            coarse_lons[y][x] = x;
            coarse_temperature[y][x] = 2 * y * y + x * x
        }
    }
    coarse_grid = gridpp::Grid(lats, lons)

    fine_lats = gridpp::init_vec2(61, 51);
    fine_lons = gridpp::init_vec2(61, 51);
    for(int y = 0; y < 61; y++) {
        for(int x = 0; x < 51; x++) {
            fine_lats[y][x] = y / 10;
            fine_lons[y][x] = x / 10;
        }
    }
    fine_grid = gridpp::Grid(lats, lons)

    // Perform interpolation
    fine_temperature = gridpp::bilinear(coarse_grid, fine_grid, coarse_temperature)
