How to integrate 3-dimensional numerical array into one dimension using Parallel Computing Toolbox?
显示 更早的评论
I have a 3-dimensional array X to be numerically integrated with trapz function. The size of array is
size(X) = p,q,r
and the third dimension (size r) is to be integrated with an integral variable given by a vactor vx whose length is r. The result Y will be 2-dimensional matrix as
size(Y) = p,q
Then, how to calculate this numerical integration using GPU with Parallel Computing Toolbox?
Thank you.

Xd= distributed(X, 3) % distributed along 3rd dim
Y = trapz(Xd, 3); % trapz support parallel processing for distributed input array
It might be better to use the 1st dimension as the integration dimension.

% Try the following along the 1st dim
% The syntax with dim is for the so-called 'Composite array', see doc
% distributed
xd = distributed(rand(20,8,6));
y = squeeze(trapz(xd))
