Hi. I have a 75*4 table. The table describes 3 classes, where 1:25 = class1, 26:50 = class2, and 51:75 = class3.
For my code, I would like to only pull the first 5 points from each class to create a new 15*4 matrix. However, when I run my code, I receive an error. Here is the code below:
Table15 = Table75([1:5,:],[25:30,:],[50:55,:]);
What could be wrong? Thanks

Your first array has 5 rows while the others have 6. After you get done slapping your forehead, you might try this:
Table15 = Table75([1:5,:],[26:30,:],[51:55,:]);
or similar.
