The following script works finely in for loop, but I need to implement parfor to speed up. I am looking for help how to implement parfor in the following nested for loop. Many thanks for your kind help.
Z_anom = zeros(n,m);
d = 0;
for y = 1:n
for c_day = 1:m
d = d + 1;
g = 0; % counter for the grid point
for i = 1:nlat
for j = 1:nlon
g = g + 1;
Z_anom(d,g) = (Z(c_day,y,i,j) - Z5(c_day,i,j))*sqrt(cosd(datalat(i)));
end
end
end
end

Dear OCDER it is not missed. Y is year c_day is day of the season and z5 is averaged over the year then subtract from z to get anomoloud

Hm, something isn't adding up.
Z_anom = zero(n, m);
for y = 1:n
for c_day = 1:m
d = d+1;
...
Z_anom(d, g) = ...
end
end
This means size of Z_anom will [n*m, nlat*nlon], and NOT [m, n] as you started out with.
Also, datalat size is [80, 80], but it seems you are accessing i from 1:nlat, where nlat = 80?
Please provide the size of all variable as per my 1st comment.
