How do I slice a matrix by the values in a certain column?

I have a large "master" table that I read in as a matrix. I wanted to create new matrices for each "height" value (there are 5: S, 1T, 10B, 4B, and 1B). Right now I have done this the "dumb" way by just sorting by height and creating new csv tables to read in but that is not a good solution at all. Is there a way to loop through the matrix and save all the rows for appropriate heights? (or another parameter that I want to group/sort by).

I have attached a screenshot of the table I am working with.

I hope you can understand my question. I am having a hard time putting what I want to do into words...

This is how I am reading in data so far...

weekly = readtable('MasterSampleLog_weekly_v1_withNO3.csv');

samples.SampleID = weekly.Sample_ID;

samples.TA = weekly.TA;

samples.DIC = weekly.DIC;

samples.Temp = weekly.Temperature;

samples.Sal = weekly.SAL;

samples.Height = weekly.height;

samples.PH = weekly.ph;

Look for strcmp(), regexp(). Use curly braces to select data in table (weekly{:,1})

B = [0.02,4.88,-3.21,2;0.56,3.9,-2.7,2;0.91,2.2,0.13,1;1.43,0.41,-1.02,3;0.00,1.9,-3.4,2;2.7,0.5,-4.0,3]

% to get the matrix where 4th column == 2

B(B(:,4)==2,:)
