Ok. The following fortran objects are ready to use: f1
import matplotlib.pyplot as plt import numpy as np
xx, yy = np.meshgrid(np.linspace(-10, 10, 100), np.linspace(-10, 10, 100)) %timeit zz = f1(xx, yy)
812 ns ± 33.6 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
# Some example data x_min, x_max, y_min, y_max = -2*np.pi, 2*np.pi, -2*np.pi, 2*np.pi f = [[f1(x, y) for x in np.linspace(x_min, x_max, num=500)] for y in np.linspace(y_min, y_max, num=500)] # Make the plot plt.figure(figsize=(10, 7)) plt.imshow(f, interpolation="bicubic", origin="lower", extent=[x_min, x_max, y_min, y_max]) plt.colorbar() plt.title(r"Title here (remove for papers)") plt.xlabel(r"Description of $x$ coordinate (units)") plt.ylabel(r"Description of $y$ coordinate (units)") plt.tight_layout()
