How to perform the following data splitting?

There are vectors X,Y,T all of these have the same size

I want to split these 3 vectors and store the splitted data in 3 arraies X_array y_array T_array

The splitting will be according to a specific range

for example:

split X and Y according to T

T contains time data from 5.2 to 10 (i,e T=[5.2,5.2002,.........................5.202, ................10])

I want to split these vectors every 0.002 of T

for example include all the data of X in one vector until T reach 5.202 then store in the first cell in the array,then include all the data of X in one vector until T reach 5.204 then store in the 2nd cell in the array,,, and so on

similar to Y and T

%Random data

t = 5.2:0.002:5.3;

x = 1:numel(t);

%Define bins to group data into

cats = min(t):0.02:max(t);

%Group the data according to the bins defined

idx = discretize(t,cats);

%Split the data according to groups and store in a cell array

%Do the same for y as well

X = splitapply(@(k) {k}, x, idx)

X'

idx = round((T(:)-5.2)/0.02) + 1;

Xgrouped = accumarray(idx, X(:), [], @(vals){vals});

Ygrouped = accumarray(idx, Y(:), [], @(vals){vals});

Tgrouped = accumarray(idx, T(:), [], @(vals){vals});
