首先,需要导入numpy库,然后使用以下代码来将上述Python代码转换为C语言:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <numpy/arrayobject.h>
void shift_rows(int rows, int cols, int offsets, double *src, double *dst) {
srand(time(NULL));
for (int y = 0; y < rows - offsets; y++) {
for (int x = 0; x < cols - offsets; x++) {
int random_num = rand() % offsets;
int src_idx = y * cols + x + random_num * cols + random_num;
int dst_idx = y * cols + x;
dst[dst_idx] = src[src_idx];
}
}
}
void main() {
// Assuming 'src' and 'dst' are 2D numpy arrays of doubles, with shape (rows, cols)
PyArrayObject* py_src;
PyArrayObject* py_dst;
int rows, cols, offsets;
// ... code to initialize 'py_src', 'py_dst', 'rows', 'cols', 'offsets' ...
double* src_data = (double*)PyArray_DATA(py_src);
double* dst_data = (double*)PyArray_DATA(py_dst);
shift_rows(rows, cols, offsets, src_data, dst_data);
// ... code to use 'py_dst' ...
}
