Does any one know how to optimize this code so that it runs faster:
for i=1:iNZ;
if iPointsinSlice>0;
for m=1:iNX;
for l=1:iNY;
if SliceMaskUr(m,l)==1;
DoseCubeU(m,l,i)=100*SumDose(m,l,i)/RX_Dose;
end
end
end
end
end
Thanks a lot!

First of all, it appears that each time through the outer-most loop (the first one), the variable iPointsinSlice does not change. Therefore, you can simplify to
for i=1:iNZ;
for m=1:iNX;
for l=1:iNY;
if SliceMaskUr(m,l)==1;
DoseCubeU(m,l,i)=100*SumDose(m,l,i)/RX_Dose;
end
end
end
end
but i bet you actually mean to have some expression that depends on i execute before the loop that iterates over m.
