Using a matrix to define which rows to display from another

I have a matrix that describes the rows i want to pull out and display from a matrix. I need to get the middle three rows out of the matrix. I took the median of the first column and then made a column with the values of the rows I need. Can I use the matrix to define the rows? M_med = median(Estress); medloc = find(Estress(:,1)==M_med); medloc1 = medloc + 1; medloc2 = medloc - 1; med=[medloc2, medloc, medloc1] M =

First of all you just shared the details of M , we don’t know the rest of the datas.

Thanks for the reply so fast the commented part at the bottom is the matrix I would like to use to pull the data from the 4 sets I am not allowed to hardcore the row numbers as the final data set might be a different length although it will be odd

[John William Meisenheimer]

It’s just the median and the two lines surrounding it
