Iterating and subsetting for a plot in Matlab

Good day,

I need help in subsetting my output and running a plot. This is my challenge:

I have an output of the shape A = (500,844). The row is for 5 different group, meaning that participant A1 =(1:100, 844), A2 =(101-200,844).... A5 =(401-500,844)

What I intend to do is do a plot on thesame graph for the five different groups. I can't do it one by one because over time the size row A ca change but the column size remain constant all through.

Is this possible?

As I showed another recent poster, <How-can-i-easily-extract-element-from-a-big-matrix> don't try to infer something from the position; compute and use a grouping variable that identifies the groups. Tables are often convenient but one can use grouping variables without -- see findgroups and splitapply

Thank you. This helps
