Find corresponding values of discritized data after using splitapply

I have a 3384x5 array of which the first and last 20 rows are shown in the pictures below.

With the help of Cris LaPierre I was able to discretize my data (https://nl.mathworks.com/matlabcentral/answers/583103-find-maximum-value-of-array-within-specified-range-consecutively?s_tid=prof_contriblnk)

I wanted to do a similar process as in the mentioned in the link.

Code so far:

% % Define edges of ranges
rng_x = -0.06:0.011:0.061;
% Assign the data of column 1 to a predefined range
disc_x = discretize(x,rng_x);
% Group the data of column 1
slice_x = splitapply(@(x) {x},x,disc_x);

As can be seen in the figure below the splitapply did what I intented it to be, it grouped the data of column 1 in each defined range. Thus:

Every value of column 1 lying between -0.06 and -0.049 is grouped into the first cell (269x1 double)

Every value of column 1 lying between -0.049 and -0.038 is grouped into the second cell (340x1 double)

And so on...

Problem: How can I retrieve the values of the 2nd column and 3th that correspond to the grouped data of column 1?

if x is extracted as the first column of your array A

slice_x = splitapply(@(x) {x}, A, disc_x);

Thank you so much!
