How about we start by adding adaptive grid resolution? This way we can adjust our grid resolution dynamically based on intensity gradients within the PSF. Here’s how you could modify your existing code: python import numpy as np def adaptive_meshgrid(size): x_centered_grid_size_factor = lambda x : x if abs(x) <= size //4 else x // (abs(x)**0.5) x_adapted_grid_size_factors=[adaptive_grid_size_factor(x) for x in range(-size//2,size//2)] y_adapted_grid_size_factors=[adaptive_grid_size_factor(y) for y in range(-size//2,size//2)] xx_adapted , yy_adapted=np.meshgrid(np.array(x_adapted_grid_size_factors),np.array(y_adapted_grid_size_factors)) return xx_adapted , yy_adapted def make_psf_image(fwhm,size): #… # replace original meshgrid call with adaptive one xx , yy=adaptive_meshgrid(size) r=np.sqrt(xx**2 + yy**2) psf_1d=gauss_1d(r,fwhm) psf_1d/=psf_1d.sum() psf_image=psf_1d.reshape((size,size)) return psf_image This modification will create an adaptive grid that changes resolution based on distance from center. # hmm interesting but what if i want multi-dimensional gaussian distributions not just radial distances # Great idea! We can extend your function to handle multi-dimensional Gaussian distributions by allowing you to specify multiple FWHM values along different dimensions. Here’s how you can modify your existing code: python import numpy as np def gauss_nd(grid_coords, fwhms): sigma_factors = [(fw / (np.sqrt(8 * np.log(2)))) for fw in fwhms] exponent_terms = [((coord / sigma)**2) for coord, sigma in zip(grid_coords,sigma_factors)] exponent_summed_term=np.sum(exponent_terms,axis=0) return np.exp(-exponent_summed_term) def make_psd_image(fwhms,size): #… x=np.linspace(-int(size/2),int(size/2),size) y=np.linspace(-int(size/2),int(size/2),size) xx , yy=np.meshgrid(x,y) r_multi_dim=[xx ,yy] psf_nd=gauss_nd(r_multi_dim,fwhms) psf_nd/=psf_nd.sum() psf_image=psf_nd.reshape((size,size)) return psf_image This modification allows you to pass multiple FWHM values corresponding to each dimension. # ok now let’s try something else how about implementing parallel processing capabilities using multiprocessing library # Sure! We can use Python’s `multiprocessing` library to parallelize parts of your computation—specifically when calculating values over large grids. Here’s how you could do it: python import numpy as np from multiprocessing import Pool def parallel_gauss_chunk(chunk_data): # Unpack chunk data into coordinates and FWHM value(s). coords_chunk, fwhms_chunk=(chunk_data[:len(chunk_data)//len(fhwms)],chunk_data[len(chunk_data)//len(fhwms):]) return gauss_nd(coords_chunk,fhwms_chunk) def make_parallel_psd_image(fhwms,size,num_workers=4): #… x=np.linspace(-int(size/2),int(size/psize)), int(size/psize)) y=np.linspace(-int(size/pefficiently)/efficiency))/efficiency,int(efficiency)))/efficiency,int(efficiency))/efficiency)) xx , yy=np.meshgrid(x,y) r_multi_dim=[xx.flatten() ,yy.flatten()] num_chunks=len(r_multi_dim)/num_workers chunks=[r_multi_dim[i:i+num_chunks] + fhwms_chunk]*num_workers with Pool(num_workers) as pool: results_list=pool.map(parallel_gauss_chunk,chunks) results_combined=np.concatenate(results_list).reshape((size,size)) results_combined/=results_combined.sum() return results_combined In this version: – The data is split into chunks. – Each chunk is processed independently across multiple workers. – The results are combined back together at the end. This should significantly speed up computation time when dealing with very large grids!<|end|) userWhat does it mean when someone says they are "busting their butt"? |
