Dear Coder, The objective is to sort a matrix B with respect to the number in a vector A. The following code was implement to achieve the objective. However, I wonder if another more compact (w/o the FOR loop) can also be realize?. I really appreciate for any suggestion.
load('help_sort.mat');
RefMats=RefMat;
ToSorts=ToSort;
c_m=1;
row_locv_CELL=zeros(1,size(RefMats,1));
for f_x=1:size(RefMats,1)
row_locv_CELL(c_m)=find(ToSorts(:,1)==RefMats(f_x));
c_m=c_m+1;
end
relative2REF=ToSorts(((row_locv_CELL))',:);

[~,ii] = ismember(RefMat,ToSort(:,1));
relative2REF = ToSort(ii,:);
