See https://www.mathworks.com/help/matlab/ref/if.html (to better understand about if statements), when an if condition is used it needs to have an end
elseif case_matrix(p,1)==4
% ^^^^----- missed it

Copy and paste this code into the MATLAB Editor. Select all that text, right-click, and select the "Smart Indent" menu option. This will line up each end keyword with the other keyword whose block it completes. Ideally, if there is a for, if, while, etc. starting in the first column of the first line, the final end on the last line should also start in the first column. For your code, it doesn't.
Looking at the code pattern I agree with KALYAN ACHARJYA's answer that your last case probably should start with elseif instead of if. When I make that change and smart indent the code, now the final end lines up with the for.
