Hello, I want to group values according to the first column which repeats itself in every 5 records and displays the values side by side to build a table like representation. How can I do this? Thanks for the help.
Input:
11.1000 -0.13104830
11.1005 -0.13109738
11.1010 -0.13113159
11.1015 -0.13115123
11.1020 -0.13115658
11.1000 -0.17104830
11.1005 -0.17779738
...
Output:
11.1000 -0.13104830 -0.17104830 ...
11.1005 -0.13109738 -0.17779738 ...

Try this
M = [
11.1000 -0.13104830
11.1005 -0.13109738
11.1010 -0.13113159
11.1015 -0.13115123
11.1020 -0.13115658
11.1000 -0.17104830
11.1005 -0.17779738
11.1010 -0.13113159
11.1015 -0.13115123
11.1020 -0.13115658];
[grps, val1] = findgroups(M(:,1));
val2 = splitapply(@(x) {x.'}, M(:,2), grps);
M_out = [val1 cell2mat(val2)];
Result
>> M_out
M_out =
11.1000 -0.1310 -0.1710
11.1005 -0.1311 -0.1778
11.1010 -0.1311 -0.1311
11.1015 -0.1312 -0.1312
11.1020 -0.1312 -0.1312
