Kmeans with matrix data

Hi everyone I would need to use kmeans for a data matrix 120 * 28 where 120 is the number of elements of which I have the 28 observations in a certain period of time. Can I use kmean? How can I get a chart like this?

Attached are my details.

% k-means model
[idx C] = kmeans(pers_ML_allSim,3);

% k-means con distanza diversa da quella Euclidea 
[idx2 C2] = kmeans(pers_ML_allSim,3,"Distance","cityblock","Replicates",5);

The example image mentioned in the question is from this link : https://www.mathworks.com/help/stats/kmeans.html.

For similar results store your data in a matrix and use the same matrix in place of "X" matrix used in the code mentioned in the documentation link.
