Is it possible to execute the following code using parfor loop?
for ii = 1 : 1 : N
x_ref = X(ii); y_ref = Y(ii);
nghlst_Local = nghlst(ii, find(nghlst(ii, :))); Nl = length(nghlst_Local);
x_Local = X(nghlst_Local, 1); y_Local = Y(nghlst_Local, 1);
Phi = ones(Nl+1, Nl+1); Phi(end, end) = 0;
Bx = zeros(Nl+1,1); By = zeros(Nl+1,1); Bxx = zeros(Nl+1,1); Byy = zeros(Nl+1,1);
for jj = 1 : 1 : Nl
for kk = 1 : 1 : Nl
rx = x_Local(jj,1) - x_Local(kk,1);
ry = y_Local(jj,1) - y_Local(kk,1);
Phi(jj, kk) = 1 / sqrt( rx^2 + ry^2 + c^2);
clear rx ry
end
rx = x_ref - x_Local(jj);
ry = y_ref - y_Local(jj);
Bx(jj, 1) = -rx/(rx^2 + ry^2 + c^2)^(3/2);
end
invPhi = inv(Phi);
CX = Bx' * invPhi; CX = CX (1, 1:end-1); Wx (ii, nghlst_Local) = CX;
end
I know nested parfor loops generally give no computational benefits. So, which for loop should I change?
