Fft gpuarray x
WebI am writing a program to numerically approximate the solution of a two point boundary value problem. The code below goes through a subset of my code and uses double for loops and if statements to execute certain aspects of the code (which should only execute for specific values of n or m).I am curious if arrayfun/ceilfun in Matlab can remove these double for … WebA gpuArray object represents an array stored in GPU memory. A large number of functions in MATLAB ® and in other toolboxes support gpuArray objects, allowing you to run your code on GPUs with minimal changes to the code. To work with gpuArray objects, use any gpuArray -enabled MATLAB function such as fft, mtimes or mldivide.
